The bond between Ca atom and OH molecule is ionic. But the bond between O and H in OH is covalent.

Ionic bonds occur between the Ca2+ ion and the hydroxide ions (OH-) in calcium hydroxide. Covalent bonding is what holds the hydroxide ion itself together...there's a single bond between the O and H atom in the hydroxide ion.

Ca is bound to the two Oxygen atoms by two ionic bonds, this because Ca atom looses its two valence electrons to obtain octet state and these two electrons completely transferred each to one Oxygen atom, also each one Oxygen atom attached to one hydrogen atom by covalent bond, this makes hydrogen atom obtain octet state(2electrons in the 1s level), also both the ionic and covalent bonds of every Oxygen atom,make the Oxygen reach the octet state ( more stable).

One of the oxygen atoms lost its electrons, while the other shared its electrons with the calcium atom
