title: Rails dosn't reload class under ajax request
body: <p>I start up rails server like this:</p>
  
  <pre><code>$rails server thin -d
  </code></pre>
  
  <p>My env is development, for sure.</p>
  
  <p>If request isn't ajax, classes reload.</p>
  
  <p>On client side, I use jQuery for ajax requests.</p>
  
  <p>Snippet on client-side:</p>
  
  <pre><code>$.ajax({
      url: '/products/all',
      success: function(data) {
      $('.result').html(data);
      alert('Load was performed.');
   }
  </code></pre>
  
  <p>});</p>
