title: angular ng-select and add event
body: <p>I'm using <a href="https://github.com/ng-select/ng-select" rel="nofollow noreferrer"><code>ng-select</code></a> and on selected item fire the callback which does some logic. I face the problem, that <code>(add)</code> event does not fire when I choose the item from the list and I use the <code>(change)</code> event instead. But if I use one item twice from the list the change event not fire, because it's a change event.</p>
  <pre><code>&lt;ng-select 
      [clearSearchOnAdd]=&quot;true&quot;
      (change)=&quot;changeLeagueOwner($event)&quot;
      (add)=&quot;test()&quot; ---&gt; nothing here
      [clearable]=&quot;false&quot;
      [items]=&quot;adminLeagueMembers&quot;
      bindLabel=&quot;display_name&quot;&gt;
  &lt;/ng-select&gt;
  </code></pre>
