remove listener

Show all headers | View raw

If I add listeners like this

Show.prototype.init = function() {
   var i,
       elem,
       len = this.allItemsIds.length,
       me = this;

   for (i = 0; i < len; i++) {
     elem = document.getElementById(this.allItemsIds[i]);

     elem.addEventListener("click", function(m) {
       return function() {
         me.show(m);
       };
     }(i));
   }
};

why does doing this fail to remove any of the listeners when I pass 
valid values for 'me', 'elem' and 'i'?

elem.removeEventListener("click", function(m) {
   return function() {
     me.show(m);
   };
}(i));

Is it because event handlers can't be anonymous?
