                    </tr>
                    <tr ng-repeat="data in vm.data">
                        <td></td>
                        <td></td>
                        <td></td>
                        <td><input type="checkbox" ng-model="data.selected" class="duplicateRow" /></td>
                    </tr>
                    <tr>
                    <tr>

                    <button class="button pull-right"  ng-click="vm.process()">Process</button>
                    </tr>
                </table>
                    <table class="table">
                        <tr>
                            <td colspan="4">
                                <pagination ng-if="renderpagination" page-number='' page-count="" total-records="" api-url="duplicate-student"></pagination>
                            </td>
                        </tr>
                    </table>
           </div>
        </div>

Java script file

vm.selectAll =function(){
      angular.forEach(vm.data, function(data){
       data.selected=true;
      });
    }
    vm.selectedUsers = [];

    vm.process = function() {
      vm.selectedUsers.splice(0, vm.selectedUsers.length);
      for (var i in vm.data) {
           vm.selectedUsers.push(vm.data[i]);
      }
       $scope.uncheckAll = function() {
    $scope.selectedUsers.splice(0, $scope.selectedUsers.length);
}
