Enemy character not being pushed back when hit anf capsule collider not generating hit event

Enemy character not being pushed back when hit anf capsule collider not generating hit event. I attached a sphere collided to my character hands and this collided can push object in the scene when they are hit because I simulate physics on the objects. But the sphere can not push the enemy character, who is standing in an idle pose.

under collision section in the details panel you have generate hit events set to true right?
