title: AngularJS Select other option and get value from textbox
body: <p>Using AngularJS I have a list of selected option and one additional "New" option. What I am trying to do is, when "New" option is chosen it will show a text-box to add a new value. </p>
  
  <pre><code>&lt;select ng-model="group.name" ng-options="bl.Name for bl in Groups" &gt;
        &lt;option value="VALUE FROM TEXT BOX"&gt;New&lt;/option&gt;
  &lt;/select&gt; 
  
  &lt;div class="col-md-4" ng-show="WHEN NEW OPTION IS Chosen "&gt;
  &lt;input class="text-box" type="text" name="NewValue" ng-model="group.name" /&gt;
  &lt;/div&gt;
  </code></pre>
