Why is only the first row is being displayed from JSON list

I have the following table:

<div data-ng-app="myApp">
    <div data-ng-controller="MyCtrl">
        <form>
            <table>
                <tr>
                    <td><b>ID</b></td>
                    <td><b>Name</b></td>
                    <td><b>Surname</b></td>
                    <td><b>House</b></td>
                    <td><b>Address</b></td>
                    <td><b>Locality</b></td>
                    <td><b>Contact1</b></td>
                    <td><b>Contact2</b></td>
                    <td><b>Contact3</b></td>
                    <td><b>Reply</b></td>
                </tr>
                <tr><td></td></tr>
                <tr ng-repeat="telesale in telesales">
                    <td>{{telesale.ID}}</td>
                    <td>{{telesale.Name}}</td>
                    <td>{{telesale.Surname}}</td>
                    <td>{{telesale.House}}</td>
                    <td>{{telesale.Address}}</td>
                    <td>{{telesale.Locality}}</td>
                    <td>{{telesale.Contact1}}</td>
                    <td>{{telesale.Contact2}}</td>
                    <td>{{telesale.Contact3}}</td>
                    <td>{{telesale.Reply}}</td>
                </tr>
            </table>
        </form>
    </div>
  </div>

controller:

<script type="text/javascript">
  var myApp = angular.module('myApp', []);

  myApp.controller('MyCtrl', ['$scope', '$http', function ($scope, $http) {

      GetPersons();

      function GetPersons() {
          $http({
              method: 'GET',

              url: '/api/data'
          }).
        success(function (data) {
            if (data != null || data != 'undefined') {
                console.log(data);
                $scope.telesales = data;
            }
        })
      .error(function (error) {
          $window.alert("Unable to retrieve people" + error.message);
      });
      }

  } ]);

The data is being retrieved from an api controller which returns a list of 40 objects, however only the first object is being displayed in the table. Why could this be happening?

It looks as if the second (and the rest of the objects) are being passed as localities which is an foreign key of another table

API Code:

public HttpResponseMessage GetPeople()
    {
        List<CommonLayer.Telesales> list = new BusinessLayer.Telesales().getUserSession(User.Identity.Name);
        //List<CommonLayer.Localities> list = new BusinessLayer.Localities().getAllLocalities();
        if (list.Count > 1)
        {
            return new HttpResponseMessage()
            {
                Content = new StringContent(JArray.FromObject(list).ToString(), Encoding.UTF8, "application/json")
            };
        }
        else
        {
            return null;
        }
    }
