title: How to bind/unbind window events in backbone view
body: <p>I need to bind event on window object inside backbone view and when navigated to other backbone view i want to unbind window event. Is there any efficient way to do this in the backbone??</p>
  
  <p>example:</p>
  
  <pre><code>class Example.Views.EntriesList extends Backbone.View
  
    initialize: -&gt;
  
      $(window).unbind('scroll').on 'scroll', _.bind(@scroll, this)
  </code></pre>
  
  <p>Above code works perfect for this view but when navigated to different backbone view then scroll bind is still present. I wanted to remove all the events binded to window when view changes.</p>
