title: Changing active tab using angular
body: <p>Angular tab change on new value?</p>
  
  <pre><code>&lt;ul class="nav nav-tabs"&gt;
      &lt;li class="active"&gt;
          &lt;a class="A" data-target="#A"&gt;Nye({{c.data.feil_nye_ant}})&lt;/a&gt;
      &lt;/li&gt;
      &lt;li class="nav"&gt;
          &lt;a class="B" data-target="#B"&gt;Aktive({{c.data.feil_aktive_ant}})&lt;/a&gt;
      &lt;/li&gt;
      &lt;li class="nav"&gt;
          &lt;a class="C" data-target="#C"&gt;HASTER({{c.data.feil_haster_ant}})&lt;/a&gt;
      &lt;/li&gt;
      &lt;li class="nav"&gt;
          &lt;a class="D" data-target="#D"&gt;Ferdige({{c.data.feil_ferdig_ant}})&lt;/a&gt;
      &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>Need to draw focus by opening the "HASTER" tab (means "urgent"), when the value of <code>c.data.feil_haster_ant</code> is updated.</p>
