Datetimepicker only showing some parts of the picker function - php

Question

I'm trying to get the datetimepicker working that can be found here
I installed this package using bower and linked all the stylesheets / js files.
When I visit the page I can only see some parts of the the actual datepicker.
Here are some pictures to have a better look:

<span class="input-group-addon">

</span>
</div>
</div>
</div>
<script type="text/javascript">
$(function () {
$('#datetimepicker1').datetimepicker();
});
</script>

#endsection
What am I missing here?

Try specifying the format:
$('#datetimepicker1').datetimepicker({
format: 'MM/dd/YYYY'
});
According to the documentation, the format specified in the options defines what components are shown.
