How to get Attached SkeletalMeshes Simulated?

I have a Character and i want to attach a skeletal mesh with simulated bones.
i put the stuff together in a blue print but the attached mesh wont move a bit.
in the physics asset the of the skeletal, i want to attach every thing looks fine.
and when i put asset direct in the level, it gets simulated to but not ■■■ attached object…

isnt it possible??
