Using a button's function on INIT

1

Sorry, I am a total AS3 noob.
I am creating a small file, using procedural programming, not ready for OOP.

I have button that adds a MC to the stage from the library. Is there a way to re-use the same function on page load?


function addCard(evt:Event):void
{
	//do stuff
	addChild(card);
}
mybutton.addEventListener(MouseEvent.MOUSE_UP, addCard);

is there a way to re-use addCard()? AS2 allowed for just calling the function


// doesn't work
addCard();

// not sure what to use for this, or if that will even work
addEventListener(??, addCard);
