Removing the dreaded annonymous function event listener

I have a function I’m using to add my listeners to a page but I need a way to globally clear them. No matter how I try, I can’t give the functions a reference to later be emptied completely so they could be re-added later.

proto.handlerFunc = {};



proto.addListener = function (evt, handler) {

    var self = this;

    this.handlerFunc = function () {

        handler.apply(self);

    }

    this.someObj.addEventListener(evt, this.handlerFunc, false);

}    

proto.removeListener = function (evt) {

    var self = this;

    this.myVideo.removeEventListener(evt, this.handlerFunc, false);

    this.handlerFunc = null;

}
