They sound like they need that new tank now. 4" long in 4 months says you are doing a good job caring for them, but even the best of care will only go so far it the bowl or tank is too small. If these are the long and thinner looking goldfish, they would really need a huge tank to grow to adults, they can get over a foot long in a tank and 18" in a big pond. I would suggest as the next step you get a 30 gallon or a 55 gallon tank. That will last them several years.
Getting a filter for the tank will be the best idea since you don't want to have to clean put a 55 gallon tank every few days. It will also keep them healthier and the water more stable.

Wow. You clean you tank every other day? I suppose that with a bowl that would be required. I would suggest you go to Wal-Mart and pick yourself up a cheap 10 gallon tank. As for filtering, I personally use a Gravel type (bubbles on each side in the back) in addition to a "Waterfall" type. You will also need an air pump. Remember, bigger is better. With you cleaning out the tank every other day, they got plenty of oxygen. That is the biggest reason your fish still seem "happy." Goldfish generally do not require a heater because their water is colder than Tropical fish (you will notice the two split in Wal-Mart, usually with the sink between them.) Also, goldfish let off a LOT of ammonia in their waste, so do not try to add any tropical fish to the tank. If you decide to just keep the bowl, do NOT over fill it. If you fill it to near the top, there is less surface area for the fish to get their oxygen. Just remember. The fish will grow to the maximum size their environments will let them. In other words, Bigger Tank = Bigger Fish...

Yes, you should move them into a larger aquarium as soon as possible. A good rule of thumb is to have at least ten gallons per goldfish being kept in the tank.
And yes, they do grow quite large, five to eight inches or more, depending on what type they are.
And yes, you should have a proper filter, not only does this clean the tank, it also helps make sure the fish are getting enough oxygen in the water.

To live their full lives (approximately 20 yrs and up to 8 inches!), goldfish require a 10 gallon per fish tank with extra filtration. They put out a TON of ammonia and this is toxic to your fish. In a bowl, you have no way of removing the ammonia short of waiting for it to build up and emptying the water. In a fish tank with a filter (no undergravel ones please), the ammonia will peak and then a new bacteria, nitrite forms. Ammonia is toxic as it burns the fish's eyes, scales and worse..gills (think of the burning that occurs on a baby's skin with diaper rash). Nitrite is also toxic as it interferes with your fish's ability to absorb oxygen. Nitrite shows up for a couple of weeks and then a new bacteria comes..nitrate..the good bacteria. When kept at levels of 20 parts per million on a test kit for nitrate, the tank is perfectly cycled.
With this method, you'll only have to change about 25 - 30% of the water once every week or 2. Your fish will have plenty of room to grow and swim..and lots of fresh water.
While it is true that if you keep the fish in the bowl, you will stunt their growth, this will cause disease and early death. The internal organs will grow and deform, causing kidneys, etc to not perform properly.
If you have 2 of them, put them into a 20 gallon tank with a hang on the back filter meant for a 30 gallon tank and they'll live long and happy lives :)

well, most people would condemn you for putting fish in a bowl with out a heater or a filter or anything like that...but you can tell them to go suck it; honestly, fish do good in tanks that the heat is regulated in and tanks that have good filtration systems but its not necessary for all fish (goldfish, for example)
now with that said, the rule of thumb is one inch of fish per one gallon of water. What this means is if each of your fish is about 4 inches long then you should picture them all lined up head to tail fin and imagine how many inches along all the fish are toghether then however many inches long all the fish are together is how many gallons the fish tank/bowl should be
for example, if you have two goldfish at 4 inches each then you should have a tank/bowl with a minimum of 8 gallons of water in it; or if you have 3 goldfish at 4 inches each then you should have a tank/bowl with a minimum of 12 gallons of water in it
keep in mind that most species of goldfish will "grow into" their tank/bowl what this means is that if you keep them in a smaller tank then they won't grow as big as they could, or if you move them into a bigger tank, they will grow bigger, at that point you shouldn't put them back in the smaller tank...so word of advice pick out the biggest size tank/bowl you plan to give them and let them grow into that, never move them back into a smaller tank/bowl, so be sure of the size before you buy it
good luck

Gold fish waste a lot so don't be surprised, tank size and how many water changes per week?

They will most likely be just fine in your tank. Goldfish grow to the size of their environment. If you leave them there, they will stay the size fitting their tank. If you want them bigger, get a bigger tank. That simple.

goldfish grow HUGE if you buy them a big tank but if you get them a small one they just stay sort of small-ish. :-)
