title: history.pushState - not working?
body: <p>I want to change html without reload. I do it like:</p>
  
  <pre><code>$('#left_menu_item').click(function(e) {
      if (!!(window.history &amp;&amp; history.pushState)) {
          e.preventDefault();
          history.pushState(null, null, newUrl);
      }
  });
  </code></pre>
  
  <p>It works correctly. But if I want to go back with "Back" button - browser change url on previous, but it not reload page. Why?</p>
