HTML5 Canvas: Calling a parent function

Hey guys

I'm currently banging my head against a brick wall trying to call a parent function with the HTML5 Canvas.

I have the following code on the stage:

function fromStage()

{

  console.log("This is on the stage");

}

fromStage();

This correctly outputs that message to the console in the browser.

However, I have a button within a movie clip that I want to call this function from, my code in that movie clip is as follows:

this.theButton.addEventListener("click", fl_MouseClickHandler.bind(this));

this.theButton.name = "theButton";

function fl_MouseClickHandler(e)

{

  this.parent.fromStage();

}

However, this doesn't appear to be working, any ideas?

Thanks
