Is is possible to bind an action in bootstrap function?

I would like to handle some external functions (phonegap sound) when the user click in a button that was inside my animation, what is the best way to do that?

AdobeEdge.bootstrapCallback(function(compId) {

// "comp" is now equivalent to the Stage's "sym" variable.

comp = AdobeEdge.getComposition(compId).getStage();

// is it possible? how?

Symbol.bindElementAction(compId, symbolName, "${_ButtonNext2}", "click", function(sym, e) {

         sym.play("dois");

      });

//comp.getStage().getSymbol("rotatingSquare").play();

});

Best Regards
