I'm trying to use date range picker but I can't seem to make it work.

<script type="text/javascript" src="//cdn.jsdelivr.net/jquery/1/jquery.min.js"></script>
<script type="text/javascript" src="//cdn.jsdelivr.net/momentjs/latest/moment.min.js"></script>
<link rel="stylesheet" type="text/css" href="//cdn.jsdelivr.net/bootstrap/3/css/bootstrap.css" />

<script type="text/javascript" 
src="//cdn.jsdelivr.net/bootstrap.daterangepicker/2/daterangepicker.js"></script>
<link rel="stylesheet" type="text/css" href="//cdn.jsdelivr.net/bootstrap.daterangepicker/2/daterangepicker.css" />

.

<input type="text" name="daterange" value="01/01/2015 - 01/31/2015" />

<script type="text/javascript">
$(function() {
$('input[name="daterange"]').daterangepicker();
});
</script>

I don't understand why it doesn't show the calendar. Any help would be appreciated.
