Hi Jeet!

Only bind the handler once:

var popupmenuBound = false;
$("#onclickpopupmenu").bind("click",function(){
  alert("this can execute multiple times");
  if (!popupmenuBound) {
    $("#popupmenuok").bind("click",function(){
      alert("this has to be triggered only once eventhough the parent event trigger multiple times");
    });
    popupmenuBound = true;
  }
});
