var JavascriptHelper = Backbone.Model.extend("JavascriptHelper",
        {}, // never initialized as an instance
        {
            myFn: function() {
                $('.selector').live('click', function() {
                    this.anotherFn(); // FAIL!
                });
            },

            anotherFn: function() {
                alert('This is never called from myFn()');
            }
        }
    );

The usual _.bindAll(this, ...) approach won't work here because I am never initializing this model as an instance. Any ideas? Thanks.
