Getting null on the place of Object

programming flash

Hello guys ,

I am storing the current object in a current_target, when hittest is true and dispathing an event to document class.
Here is my code

if(evt.target.hitTestObject(_targetCont))			{
				 current_target=new MovieClip();
				current_target = evt.target as MovieClip;
				
				dispatchEvent(new HitEvents(HitEvents.DROPPED_TO_TARGET));
				
			}
public function get CurrentTarget()
		{
			
			return(current_target as MovieClip);
		}

and then i have added an event listener in document class
and in the function I am tracing the “current_target” but its returning null.
