title: Vue form select emit event when the same element is selected
body: <p>When I attach the '@change' property to a form input, e.g.</p>
  
  <pre><code>&lt;select v-model="data" @change="handler"&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>It is only triggered when a different option is selected. How do I trigger the handler function even when the same option is chosen again?</p>
