Any reason why my code isn't executing the "stop" action?

Any reason why my code isn't executing the "stop" action?

sym.getComposition().getStage().getSymbol("_001").$("_002").$("_003"). bind('mouseenter',function(e){

e.preventDefault();

$(this).unbind('mouseenter');

sym.getComposition().getStage().getSymbol("_001").$("_002").$("_003"). stop("over");

});

See my file here http://twistedpancreas.com/edge/misc/dropDownNotWorking.zip

The dropdown should change to orange when rolled over, but it's not

Any help is appreciated.
