I think it can be really hit and miss at 22 weeks as there is still sooooo much room for the baby to move around in - its difficult to know where to place a hand to get a direct kick.

DP was lucky enough to feel an outside movement at 20 weeks (but we had had a rotten week, so it felt like we deserved it) but then it was very sporadic after that.
Keep trying though, I'm sure that the baby will know it is your partner's hand on your belly and begin to know and bond with him through that
