I am new to Angularjs and I was following a tutorial but I got the error in the title.

HTML code:

<pre lang="HTML"><div data-ng-app="myApp">
    <div data-ng-controller="MyCtrl">
    <form>
        <table>
        <tr style="font-weight: bold">
          <td>ID</td>
          <td>Name</td>
          <td>Surname</td>
          <td>House</td>
          <td>Address</td>
          <td>Locality</td>
          <td>Contact</td>
          <td>Contact 2</td>
          <td>Contact 3</td>
          <td>Reply</td>
          <td>Edit</td>
        </tr>
        <tr data-ng-repeat="person in persons">
            <td>{{person.ID}}</td>
            <td>{{person.Name}}</td>
            <td>{{person.Surname}}</td>
            <td>{{person.House}}</td>
            <td>{{person.Address}}</td>
        </tr>


        </table>
    </form>
    </div>
</div>

<script type="text/javascript">

            $scope.status = 'Unable to retrieve people' + error.message; 
        });
    }
} ]);
</script>

public class DataController : ApiController
    {
        //GET api/data
