如何在子控制器中为bootstrap模式实例执行方法？

Question

我有一个我从父控制器打开的引导模式实例，现在我在复选框checkedValue上添加了我试图从子控制器调用的方法，但我收到错误Cannot read property 'attuid' of undefined at ChildScope.$scope.checkedValue (newUserModal.controller.js:22)任何想法我怎样才能在子控制器中调用方法？

newUserModal.html

<tr ng-repeat="user in userList track by $index">
          <td st-ratio="20">{{user.attuid}}</td>
          <td st-ratio="30">{{user.firstName}} {{user.lastName}}</td>
          <td st-ratio="15" ng-bind-html="user.type"></td>
          <td st-ratio="15">{{user.email}}</td>
          <td><input type="checkbox" ng-model="user.selected" ng-click="checkedValue(user)"> </td>
          <!--<td st-ratio="20" class="text-right">
            <button type="button" ng-click="editUser($index, user)" class="btn btn-primary">
              Approve
            </button>
          </td>-->
        </tr>

parent.controller.js

 $scope.newUserListModal = function () {
        $scope.modalInstance = $uibModal.open({
                     templateUrl: 'app/access/accessModal/newUserModal.html',
                     controller: 'AccessModalCtrl',
                     size: 'lg'
               });
             $scope.modalInstance.rendered.then(function () {
                 $rootScope.$broadcast('show-user-list',$scope.userList);
               });
               /*$scope.modalInstance.result.then(function(selectedUsers) {
                 console.log(selectedUsers);
               });*/
    }

child.controller.js

angular.module('angularModelerApp')
  .controller('AccessModalCtrl', function ($scope,$uibModalInstance,toastr) {
  var selectedUsers = [];
  $scope.$on('show-user-list',function(e,data){
    $scope.userList = data;
  });

    $scope.checkedValue = function(user){
           $scope.selectedUsers = $scope.selectedUsers || [];
           if(user.selected){
               $scope.selectedUsers.push({ attuid: $scope.user.attuid,
                                           firstName: $scope.user.firstName,
                                           lastName: $scope.user.lastName,
                                           email:$scope.user.email
                });
                console.log($scope.selectedUsers);
           }
       };
});
