[BS4] problems with component input

Well my site is being developed with bootstrap 4, I want to use the date picker but it doesnt work at all. I just include these files:

<link rel="stylesheet"  type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.5.0/css/bootstrap-datepicker.min.css"/>
<script type='text/javascript' src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.5.0/js/bootstrap-datepicker.min.js">
<script type='text/javascript'>
$('.datepicker').datepicker()
</script>    

And the HTML I used was just copied/pasted from the documentation(the one with component/group):

<div class="input-group date">
    <input type="text" class="form-control datepicker" value="12-02-2012">
    <div class="input-group-addon">
        <i class="fa fa-calendar"></i>
    </div>
</div>

The only difference is that I replaced the span tag for glyphicon by fontawesome, other than this I dont see anything else that can cause the trouble. Is the issue caused by the removal of glyphicon? If so, when will you make this compatible with Bootstrap 4 which doesnt have glyphicon? Or am I doing something wrong myself?
