title: update existing option in select list
body: <p>Let's say that I have select list with 3 options inside:</p>
  
  <pre><code>  &lt;select&gt;
      &lt;option&gt;1&lt;/option&gt;
      &lt;option&gt;2&lt;/option&gt;
      &lt;option&gt;3&lt;/option&gt;
    &lt;/select&gt;
  </code></pre>
  
  <p>Now, I want to update one of these options, so i create textfield &amp; button.
  The option appear inside the textfield everytime i press on one of the options at the select list.
  Can someone direct me what do i need to do?</p>
