My Kadabra has no attacks!?

So, I caught an abra at level 10. And being far too lazy to level it, I stuck the thing in the day care until 16. So, supposedly at 16 it should evolve, and learn confusion. It hadnt done either. So I figured one more level and that'd happen. But now it's evolved, and still only has teleport. Its currently level 17, and now I need to know why it hasnt learned confusion? And if it wont learn confusion, can I stick it in the day care until 21 to teach it psybeam?
