<div class="input-group date" data-behavior="MemberCredit.filterDatePicker" data-date-before-field="#filter_end_date">
  <input type="text" class="form-control" id="filter_start_date" {{action filterPortfolios}}/>
   <span class="input-group-addon">
     <span class="glyphicon glyphicon-calendar"></span>
   </span>
</div>
