tying button onclick event to Backbone View

Go To StackoverFlow.com


I have a sample single-page-application in Backbone that I am messing around with. The idea is that I have a button that will trigger a refresh on a view. I am trying to get the event handler to remember 'this' as the backbone view, not the element that it was called on. No matter how much docs I read, I cant seem to make it past this mental hump.

in my view, I have

initialize: function() {'
  //i am trying to say, call render on this view when the button is clicked. I have tried all of these calls below.
  //this.$("#add-button").bind("click", this.render);


When the render function is called, the 'this' element is the button. I know what im missing is pretty easy, can someone help me out with it? Also, is this sound as coding conventions go?

If you use the View's 'delegateEvents' functionality, the scoping is taken care of for you:

var yourView = Backbone.View.extend({

  events: {
    "click #add-tweet-button" : "render"

  render: function() {
    // your render function
    return this;

This only works with elements that are 'under' the View's El. But, your example shows this.$(...), so I'm assuming this is the case.

@Edward M Smith is right, although if you need to handle a jquery event of element outside the scope of your View you might write it that way :

var yourView = Backbone.View.extend({

    initialize: function() {
        var self = this;
        $("button").click(function () {
              self.render.apply(self, arguments);


    render: function(event) {
        // this is your View here...
