title: bootstrap-datepicker lacks colums when using it on a mobile
body: <p>I have created a website using the bootstrap framework. On this website, I'm using the date-time picker and on a standard monitor, everything looks normal. Now, when viewing the same page on a mobile (Android or Iphone), it seems the date-picker lacks columns - for example, I'm lacking Wednesday and Thursday -  Anyone experienced the same issue ? </p>
  
  <pre><code>&lt;div class="col-xs-6 col-sm-6 col-md-6"&gt;
      &lt;div class="form-group"&gt;
          &lt;label&gt;Duik datum&amp;nbsp;:&amp;nbsp;&lt;/label&gt;
              &lt;input name="date_picker" id="datepicker" value="&lt;?php echo(date("d-m-Y", time())); ?&gt;" readonly&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
