Applying one function to many buttons?

function clicked(e:MouseEvent):void {

if(a == 0){
   Tweener.addTween(circle, {scaleX:5, scaleY:5, time:0.5, transition:"easeOutElastic"});
   Tweener.addTween(circle, {x:middleX, y:middleY, time:0.5, transition:"easeInOutBounce"});
   a = 1;
}else if(a == 1){
   Tweener.addTween(circle, {scaleX:1, scaleY:1, time:0.5, transition:"easeOutElastic"});
       Tweener.addTween(circle, {x: origX, y: origY, time:0.5, transition:"easeInOutBounce"});
       a = 0;
}

}

circle.addEventListener(MouseEvent.CLICK, clicked);

the addEventListener will be in a forloop and applied to all the circles that are created. But how do I have the function apply itself to all the circle(s)

How do I send an “circle” array as an argument or whatever it’s called to that clicked function.
