Angular js with custom widget : uib-pagination is not working.

Hello,
I created a simple custom widget with angular js.

The code is simple.
I added angular js asset.

however,** uib-pagination** didn't appear in UI preview.
I would like to know if I miss some part.
Any help appreciated .

Thanks.

templeate:

   <input type="text" class="form-control" placeholder="Filter" ng-model="filterText">
     <ul>
     <li ng-repeat="item in filterData = (totalItems | filter : {firstname: filterText}) 
    |  limitTo:3:3*(page-1)">  <div>{{item.firstname}}</div>
    </li>
  </ul>

    <uib-pagination class="pagination-sm pagination" total-items="filterData.length" 
     ng-model="page"
     ng-change="pageChanged()" 
     previous-text="‹" 
     next-text="›" 
     items-per-page=3> </uib- 
     pagination>

The controller is as follows.

     function searchP($scope) {
      $scope.page = 1;
