Button not working inside draggable mc

K, so I’ve got a button inside a mc. The mc is made draggable via some script on the main timeline:


mc_instance_name.onPress=function(){
this.startDrag();
}
mc_instance_name.onRelease=function(){
this.stopDrag();
}

Works fine. (this is an attachMovie clip by the way).
So i put an invisible button inside this movieclip so when pressed it would close the mc (removeMovieClip();)

Doesn't work now since the mc is now draggable. I've tried different ways to hitTest but nothing working.

Any ideas?
