title: View.stopListening() not working
body: <p><a href="http://jsfiddle.net/sbel/3KAhC/" rel="nofollow">http://jsfiddle.net/sbel/3KAhC/</a></p>
  
  <p>In this fiddle code the even though the stopListening method is called the on method is still in effect as can be seen by the output. What am I doing wrong?</p>
  
  <p>JavaScript:</p>
  
  <pre><code>// Define View
  var SomeView = Backbone.View.extend({
      initialize: function () {
          // Listen to the model
          this.model.on('change', this.render, this);
      },
  
      render: function () {
          $("#message").append("&lt;br&gt;render called");
      },
  
      close: function () {
          this.stopListening();
      }
  });
  
  var SomeModel = Backbone.Model.extend({});
  
  var someModel = new SomeModel({
      name: 'Foo'
  });
  var someView = new SomeView({
      model: someModel
  });
  
  someModel.set('name', 'Bar');
  someView.close();
  someView = null;
  someModel.set('name', 'Zoo');
  </code></pre>
