title: How to v-model a input of type date
body: <p>I have an input like so:</p>
  <pre><code>&lt;input class=&quot;input&quot; type=&quot;date&quot; v-model=&quot;dob&quot; /&gt;
  </code></pre>
  <p><code>dob</code> is initialized as null, and works properly. For example 03/05/2006 models to <code>2006-03-05T00:00:00.000+00:0</code>.
  However when <code>dob</code> is inititialized as <code>2006-03-05T00:00:00.000+00:0</code>, it doesn't show in the date input. How would I fix this.</p>
