Failed to load template: uib/template/datepicker/datepicker.html

When I click the button to select the date / time, the dropdown with the calendar / time does not appear and I get the following error in my console:

Sei que não é um bug, mas não estou conseguindo encontrar o erro do meu código, segue abaixo:

View:

 ```
   <div class="col-md-4" style="margin-left: -14px !important">
          <label class="m_top10">Data e Hora:</label>
          <p class="input-group">
            <input type="text" class="form-control" ng-click="vm.openCalendar($event, prop)" datetime-picker="dd MMM yyyy HH:mm" ng-model="vm.myDate" is-open="vm.isOpen"/>
            <span class="input-group-btn">
                <button type="button" class="btn btn-default" ng-click="vm.openCalendar($event, prop)"><i class="fa fa-calendar"></i></button>
            </span>
          </p>
   </div>

Controller:

    var vm = this;

    vm.isOpen = false;

    vm.openCalendar = function(e) {

        e.preventDefault();
        e.stopPropagation();

        vm.isOpen = true;        
    };
