title: Knob circular progress bar with ajax
body: <p>I am trying to use Knob with AJAX, and it is working, but the progress bar is not changing, only the number inside real time.</p>
  
  <p>You can check it here: www.skincannon.com </p>
  
  <p>The code is:
  HTML:</p>
  
  <pre><code>&lt;input id="val" type="text" value="0" /&gt; &lt;input type="button" value="Change" /&gt; 
  </code></pre>
  
  <p>AJAX:</p>
  
  <pre><code>$.ajax({
      type: "GET",
      url: "currentitemswidth.php",
      success: function(msg){
          $('#val').val(msg);
      }
  });
  </code></pre>
  
  <p>And I am changing the value with ajax, but the bar won't change.</p>
  
  <p>Anybody could help me? If you need further codes just tell me.</p>
  
  <p>I need something like this, but I would like to change it automatically, not by hitting the Change button: <a href="http://www.jqueryajaxphp.com/dynamically-animate-jquery-knob/" rel="nofollow">http://www.jqueryajaxphp.com/dynamically-animate-jquery-knob/</a></p>
  
  <p>Thanks</p>
