backbone.js + JQuery: 'this' reference not accessible in JQuery-Event-Handler

I'm trying to use backbone.js in my webapp. I have a View which uses the JQuery draggable plugin to make a div draggable:

var ExampleView = Backbone.View.extend({
  event开发者_运维知识库s: {
    //...
  },

  initialize: function() {
    _.bindAll(this, "render");

    this.model.bind('change', this.render);
  },

  render: function() {
      // icanhaz
      this.el = ich.kinectdevtmpl();

      $(this.el).draggable({
         drag: function() { 
                alert(this.model);

         }
      });           

    return this;
  }      

});

But in the drag event handler I can't access 'this.model' because 'this' do not refer to the view anymore. So, how can I access my View in the JQuery event handler?

this has changed and is no longer what you want. you can assign this to a variable and use that instead.

var that = this;
$(this.el).draggable({
   drag: function() { 
          alert(that.model);

   }
});
