title: Chart.js in AngularJS tabset does not render
body: <p>I am using a AngularJS module based on Chart.js to display graph. It works like a charm, but when I display a chart in a AngularJS tabset, the graph does not render if it is not the first tab.</p>
  
  <pre><code>  &lt;tabset&gt;
      &lt;tab heading="Tab 1"&gt;
          &lt;!-- OK --&gt;
          &lt;canvas class="chart chart-pie" data="[140, 160]" labels="['d1', 'd2']" legend="true"&gt;&lt;/canvas&gt;
      &lt;/tab&gt;
      &lt;tab heading="Tab 2"&gt;
          &lt;!-- Does not render --&gt;
         &lt;canvas class="chart chart-pie" data="[140, 160]" labels="['d1', 'd2']" legend="true"&gt;&lt;/canvas&gt;
      &lt;/tab&gt;
    &lt;/tabset&gt;
  </code></pre>
