title: Event handler for input+datalist
body: <p>I'd like to use something like <a href="https://stackoverflow.com/a/17658653/174728">this snippet</a></p>
  
  <pre><code>&lt;input type="text" name="product" list="productName"/&gt;
  &lt;datalist id="productName"&gt;
      &lt;option value="Pen"&gt;Pen&lt;/option&gt;
      &lt;option value="Pencil"&gt;Pencil&lt;/option&gt;
      &lt;option value="Paper"&gt;Paper&lt;/option&gt;
  &lt;/datalist&gt;
  </code></pre>
  
  <p>But I need to run some js code whenever the selection is changed (or the value edited). Is there a way to hook up an event handler for that?</p>
