title: how to make Semantic UI dropdown with allowAdditions work
body: <p>I am trying to have a Semantic UI dropdown menu which allows additions but I can seem to make it work. Indeed the <code>Add &lt;b&gt;{term}&lt;/b&gt;</code> message that is supposed to appear when adding something never seem to show up.</p>
  
  <p>Here is a very simple example to test it <a href="http://jsfiddle.net/pybxztu2/8/" rel="nofollow noreferrer">http://jsfiddle.net/pybxztu2/8/</a></p>
  
  <p>If type <code>johny</code> in the search the message doesn't show. Though if I press enter it is going through the <code>onChange</code> function.</p>
  
  <p>In addition, is it even possible to have such a menu where it would be able to add <code>bob</code>: even with the <code>forceSelection: false</code> it takes <code>boby</code> by default...</p>
  
  <p>Maybe I am just missing something in the Semantic UI doc...</p>
