Making a mob attacking you

Hello, i had make a mob with a custom AI, it's a biped. He can walk, open doors, etc... All is ok.

BUT, he can't attack me, it doesn't works.

With Agressive against entityplayer, i tried to attack him in singleplayer, he don't reacts.

I tried attack and colide too, i think it's when someone or something is attacking this mob, i'm not sure, but nothing is hapening.

I tried leap on target too, i think it works, i'm not sure that it's when mob is jumping on you when your at 1 block of him, right?

Thanks for help, i hope that my mob will kill me when i'll have some answers ^^
