title: Backbone Collections - fetch() ,success callback not working
body: <p>I am coding in Backbone Js and this is my code :</p>
  
  <pre><code>var Router, UserList, Users, router, userList;
  
      $.ajaxPrefilter(function(options, originalOptions, jqXHR) {
        return options.url = "http://backbonejs-beginner.herokuapp.com" + options.url;
      });
  
      Users = Backbone.Collection.extend({
        url: '/users'
      });
  
      UserList = Backbone.View.extend({
        el: '#app',
        render: function() {
          var users;
          users = new Users();
          return users.fetch({
            success: function() {
              return console.log("Please log something!! ");
            }
          });
        }
      });
  
      userList = new UserList();
  
      Router = Backbone.Router.extend({
        routes: {
          '': 'home'
        },
        home: function() {
          console.log('Welcome home my friend!!');
          return userList.render();
        }
      });
  
      router = new Router();
  
      Backbone.history.start();
  </code></pre>
  
  <p>But the success callback in the collection.fetch() is not working. It is not logging anything! </p>
  
  <p>Here is the JsFiddle : jsfiddle.net/9DjPY/1</p>
  
  <p>Please help me! </p>
