I just had this issue and solved it using $.noConflict();

```
<script type="text/javascript">
    var Jquery = jQuery.noConflict();
    Jquery(document).ready(function () {
        Jquery('.datepicker').datepicker({

            format: "mm/dd/yyyy",
            endDate: '+0d',
            autoclose: true

        });

      });
</script>
```
