kan ikke få min datepicker script til at virke

Jeg har planket et datepicker script herfra: https://eonasdan.github.io/bootstrap-datetimepicker/ som jeg har smidt ind i min bootstrap 3 side.Jeg kan dog ikke få datepickeren til at virker.

Mit headtag ser sådan ud:

og min datepicker ser sådan ud:

<div class="row">
        <div class='col-sm-6'>
            <div class="form-group">
                <div class='input-group date' id='datetimepicker1'>
                    <input type='text' class="form-control" />
                    <span class="input-group-addon">
                        <span class="glyphicon glyphicon-calendar"></span>
                    </span>
                </div>
            </div>
        </div>
        <script type="text/javascript">
            $(function () {
                $('#datetimepicker1').datetimepicker();
            });
        </script>
    </div>

Hvad har jeg glemt?
