Layanan WCF + JSONP

Saya memiliki layanan wcf di http://testwcfgrid.atic-solutions.com/ yang semuanya berfungsi dengan baik . Saya ingin menggunakan layanan itu di aplikasi lain dengan jQuery.ajax tetapi tidak berhasil. Web.config saya adalah:

 <system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<modules runAllManagedModulesForAllRequests="true">
  <remove name="WebDAVModule"/>

layanan wcf saya untuk membaca dan membuat:

[OperationContract]
[WebInvoke(ResponseFormat = WebMessageFormat.Json,
              RequestFormat = WebMessageFormat.Json)]
public DataSourceResult Read(int skip, int take, IEnumerable<Sort> sort, Filter filter)
{
    VoziloMassive table = new VoziloMassive();

    return table.GetVehicles().AsQueryable().Select(x => new VoziloViewModel
    {
        Id = x.Id,
        Timestamp = x.Timestamp,
        Marka = x.Marka,
        Registracija = x.Registracija,
        Vrsta = x.Vrsta,
        Flag = x.Flag
    }).ToDataSourceResult(take, skip, sort, filter);
}

[OperationContract]
public IEnumerable<VoziloViewModel> Create(IEnumerable<VoziloViewModel> vehicles)
{
    var result = new List<VoziloViewModel>();

    foreach (var vehicleViewModel in vehicles)
    {
        // Create a new Product entity and set its properties from productViewModel
        var vehicle = new VoziloViewModel
        {
            Marka = vehicleViewModel.Marka,
            Registracija = vehicleViewModel.Registracija
        };

        // store the product in the result
        result.Add(vehicle);

        // Add the entity
        VoziloMassive table = new VoziloMassive();
        table.AddVehicle(vehicle);
    }

    // Return the inserted products - the Kendo Grid needs their ProductID which is generated by SQL server during insertion

    return result.Select(x => new VoziloViewModel
    {
        Id = x.Id,
        Timestamp = x.Timestamp,
        Marka = x.Marka,
        Registracija = x.Registracija,
        Vrsta = x.Vrsta,
        Flag = x.Flag
    })
        .ToList();
}

panggilan .ajax saya:

$.ajax({
                        url: "http://testwcfgrid.atic-solutions.com/Products.svc/Read",               
                        dataType: "jsonp",
                        success: function (result) {
                            // notify the data source that the request succeeded
                            options.success(result);
                        },
                        error: function (result) {
                            // notify the data source that the request failed
                            options.error(result);
                        }
                    });

dan ini tanggapannya: http://prntscr.com/3xxdjw

Apa yang kulewatkan di sini? Saya mencoba segalanya... Saya menggunakan kontrol telerik kendo dan saya mengikuti contohnya.

Terima kasih
