programming flash

Ayumilove sent:

//Within Button1.as class 
super.dispatchEvent(new CustomEvent("your custom message or data")); 
super.dispatchEvent(new CustomEvent(CustomEvent.AYUMILOVE_EVENT));

and

var button1:Button = screenHandler.button1; 
button1.addEventListener(CustomEvent.AYUMILOVE_EVENT, triggerHandler)

each instance will have to have it’s own event, how should i pass each instance its custom event?
