title: angular time progress bar
body: <p>According to the example on their webpage i should be able to do something like this:</p>
  
  <pre><code>        &lt;timer countdown="30" interval="1000"&gt;
          &lt;div class="progress progress-striped active {{displayProgressActive}}" style="height: 30px;"&gt; Remaining
              time : {{countdown}} second{{secondsS}} ({{progressBar}}%). Activity? {{displayProgressActive}}
              &lt;div class="bar" style="min-width: 2em;width: {{progressBar}}%;"&gt;&lt;/div&gt;
          &lt;/div&gt;
      &lt;/timer&gt;
  </code></pre>
  
  <p>However the time is running down correctly but the progress bar is not moving. so apprently the <code>displayProgress</code> does not trigger.</p>
  
  <p>Can anyone help me with this?</p>
