[AS3] Assigning different variables

Hello,

Is it possible to assign different names of variables each time a function is triggered?

Since I've got a timer that triggers a functions, the function itself just adds a new object called "antwoorden" to the stage. Now, how can I let it add the new object with different kind of names, each time the function is called? For example, timer triggers for the first time: Adds "antwoordenOne" to the stage, timer triggers again: Adds "antwoordenTwo" to the stage. Again: "antwoordenThree", etc. That way I can give each object (of the same class) different kind of parameters.

The code:

timer = new Timer(4000, 6); // Timer gets triggered every 4 secs (6 times.)
timer.start();
timer.addEventListener(TimerEvent.TIMER, onTime);

private function onTime(event:TimerEvent):void
{
	tekenAntwoord();
}

private function tekenAntwoord():void
{
	antwoorden = new Antwoorden();
	antwoorden.x = Math.random()*(stageWidth - antwoorden.width);
	addChild(antwoorden);
}

Code (markup):

Anyone can help me out with this one?

Greets.
