Acces function window.resize

Hi,

I want to acces a function from an Event 'window.resize' on the stage, and the function that I need to access is in a clip called  'Graduation" in the CreationCompleted of this clip (please excuse my english)

I tried without success that

sym.$("Graduation").MadeGraduation();

and

sym.getComposition().getStage().getSymbol("Graduation").MadeGraduation();

and

sym.getComposition().getStage().$("Graduation").MadeGraduation();

any idea ?

thanks
