Calling functions inside functions

question is a simple one, how do i get the function call “testFunc” to be recognized inside this movieclips “onRelease” call ?



    public function mouseHandler ( ) {

        testMovieClip.onRelease = function() {
            
            this.stopDrag( );
            
            testFunc( );
        }
    }        
            
    public function testFunc( ):Void { 
        
        trace ( "Blah" );
    }
