title: Semantic-UI Multiple selection get values
body: <p>Based on Semantic-UI docs, <a href="https://semantic-ui.com/modules/dropdown.html#multiple-selections" rel="noreferrer" title="Multiple Selection">https://semantic-ui.com/modules/dropdown.html#multiple-selections</a></p>
  
  <p>I have following code inside angular2 template:</p>
  
  <pre><code>&lt;select id="thickness" name="thick" [(ngModel)]="form.thickness" multiple="multiple" class="ui multiple dropdown selection"&gt;
       &lt;option value=""&gt;Выбрать&lt;/option&gt;
       &lt;option value="100"&gt;100 mm&lt;/option&gt;
       &lt;option value="150"&gt;150 mm&lt;/option&gt;
       &lt;option value="200"&gt;200 mm&lt;/option&gt;
       &lt;option value="250"&gt;250 mm&lt;/option&gt;
       &lt;option value="300"&gt;300 mm&lt;/option&gt;
       &lt;option value="375"&gt;375 mm&lt;/option&gt;
       &lt;option value="400"&gt;400 mm&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>I'd like to get array of selected values from <code>Select</code> to angular model <code>form.thickness</code></p>
  
  <p>However, I am getting empty array.
  inside <code>ngOnInit</code>  I have <code>$('#thickness').dropdown();</code></p>
  
  <p><code>console.log($('#thickness').dropdown('get value'));</code> gives empty array;</p>
  
  <p>How to get values from dropdown multiple selection?</p>
