cant display values of array

I have a textbox which display the code of users

<label class="control-label">USER CODE:</label>
   <input placeholder="Enter a User Code" type="text" class="form-control" ng-model="user.userCode"/>

On a show button it calls an api which fetches the product code assigned to particular user.

<button type="button" class="btn btn-info"><i class="fa fa-hand-o-up" ng-click="getAssignedProducts(user.userCode)"></i>Show</button>

The product code is displayed in the table:-

 <label style="text-align:center;">Mapped Products:</label>
            <table cellpadding="0" cellspacing="0" style="margin:auto;">
                              <thead>
                                <tr>
                                    <th>Product Code</th>
                                </tr>
                              </thead>
                          <tbody>
                            <tr ng-repeat="row in assignedProduct track by $index">
                                <td></td>
                            </tr>
                          </tbody>
                        </table>

My api code is:-

function getAssignedProducts(userCode) {
            return $http({
                method: 'GET',
                url: '/api/user/assignedProduct?userCode=' + userCode
            });
        }

My directive code:-

scope.getAssignedProduct = function (userCode) {
               ApiServices.getAssignedProduct(userCode).then(
                        function (response) {
                              scope.assignedProduct=response.data;
                            },
                                function (err) {
                                    // Handle error here
                                    console.log('Error' + JSON.stringify(err.data));
                                });
                   }

Here, assignedProduct is an array in backend which stores string values.

What my issue is, the api is calling correctly but the data is not displaying in table.I think I am not displaying data correctly in directive. Can anyone tell me where is my mistake.
