how to delete a symbol with a click of a inside button

Hello,

I have this Symbol with a button inside. I want to click on this button and delete the Symbol.

I have the code below but it doesn't work.

sym.getComposition().getStage().getSymbol("vitrine_content").$("cachedarmes_movie").delete Symbol();

if I try to do animate the symbol. It works :

sym.getComposition().getStage().getSymbol("vitrine_content").$("cachedarmes_movie").animat e({'left':'200px'});

And I don't see why..

thanks

s.
