Does anyone know if it’s possible to link a MovieClip on the stage to a class?

I have a MovieClip on the stage called: square\_mc

and I have this Move class (see attached code).

Of course when I set the class linkage of square\_mc to the Move class, square\_mc moves down the screen, Move is working. But how would I attach the Move class to square\_mc at runtime, when it’s on the stage?

Thanks!  
Attach Code

package {  
import flash.display.MovieClip;  
import flash.events.Event;  
//  
public class Move extends MovieClip {  
//  
public function Move () {  
trace (“Move”);  
this.addEventListener(Event.ENTER\_FRAME, moveSquare);  
}  
//  
private function moveSquare (event:Event) {  
this.y += 1;  
}  
}  
}
