[Solved] Summon unit does not attack!Help!

[Geshishouhu]

Hi guys.
I made a summon ability to summon a dragon. The problem is the dragon does not attack by itself even when he is being attacked!! WHY?! The only way to make him attack is to use "A+click ground", but after he kills the enemies in that area, he goes back to the "not attack" mode. Why? Please help, I have tried everything I could do. Thanks a lot.
