        var dom = getElementById('someid');
        dom.onclick = function(){
            self.foo2(); // here I used the self reference
            //i cannot use this here, because it refer to dom
        }
    }

    this.foo2 = function(){
        var dom = getElementById('someid');
        dom.onclick = function(){
            self.foo2(); //here …
