removeEventListener is not working on if/else condition

Hello All,

It is very ridiculous that I can't remove a simple listener method :). I think this is a common problem
When I am using removeEventListener manually, i.e outside the condition its working fine, but whenever I am using it inside the if/else condition it is adding the listener in "true" mode but not removing in the "false" mode.


here is my code:

if (proAlign == true) {

trace("align Option = " + proAlign + " -- " + "this is true part");

centerAlignButton.buttonMode=true;
bookPocketAlignButton.buttonMode=true;

centerAlignButton.addEventListener(MouseEvent.CLICK,centreAlign);
bookPocketAlignButton.addEventListener(MouseEvent.CLICK,pocketAlign);

} else {
centerAlignButton.removeEventListener(MouseEvent.CLICK,centreAlign);
bookPocketAlignButton.removeEventListener(MouseEvent.CLICK,pocketAlign);

centerAlignButton.buttonMode=false;
bookPocketAlignButton.buttonMode=false;

}
