Remove alert clickHandler

Question

I have a form(MovieClip) that I popup where a user can update
their info.
Each time the profile is updated I popup an Alert saying
"Profile Updated". It's adding a new listener for each time I
update the profile. 2nd time I call it I get 2 Alerts, 3rd time 3
etc.
How do I remove these after they have been triggered? I'm
removing several others, but do not know and can't find the syntax
to remove these.

Maybe you mean this:
<?xml version="1.0" encoding="utf-8"?>
<s:Application  xmlns:fx="http://ns.adobe.com/mxml/2009"
       xmlns:s="library://ns.adobe.com/flex/spark"
       xmlns:mx="library://ns.adobe.com/flex/mx"
       creationComplete="init();">
<fx:Script>
  <![CDATA[
    public function init():void {
    addEventListener("cEvent", cEventHandler);
   private function cEventHandler (e:Event):void {
     removeEventListener("cEvent",cEventHandler);
     mx.controls.Alert.show("cEvent handled and removed");
   private function  clickHandler(e:Event):void {
    dispatchEvent(new Event("cEvent"));
  ]]>
</fx:Script>
<s:Button lable="click"  click="clickHandler(e)"/>
</s:Application>
