Edge Animate CC :: How To Call CreateJS Function

Say you need a slightly more sophisticated animation and used a CreateJS from Flash.I've placed the CreateJS in a container, and I've been able to communicate from CreateJS to Edge symbol with no problem:
 
/* js
this.onClick = function () {
var comp = $.Edge.getComposition("EDGE-25177479");
var stage = comp.getStage();
stage.getSymbol("logo").play("playLogo");
}
 
But how do it the other way, and create a function from within Edge to call upon the CreateJS canvas ("myCanvas")?I want to call a "gotoAndPlay("start");" label on the main timeline of the canvas element. My syntax is completely wrong:
 
//on click
var canvas = document.getElementById("myCanvas");
var context = canvas.getContext("2d");
stage.gotoAndPlay("start");
