title: Jquery class selector not triggering when a addClass has been used
body: <p>The following code adds a class to a DIV called 'shift' among other things.</p>
  
  <pre><code>$('.adminopen').click(function(){
          $('.backoffice').addClass('open');
          $('.maincontent').addClass('shift')
          return false
      });
  </code></pre>
  
  <p>Once this class has been added why does the next script also contained in the initial document ready section not trigger.</p>
  
  <pre><code>$('.shift').click(function(){
          $('.backoffice').removeClass('open');
          $('.maincontent').removeClass('shift');
      });
  </code></pre>
