剑道网格ajax绑定不起作用

I follow the kendo demo, and I check the data was return list of data to view, but finally the grid have not display any row.

View

@(Html.Kendo().Grid<ProductListModel>()

    .Name("grid")  
    .DataSource(dataSource => dataSource
        .Ajax()
        .Read(read => read.Action("RowTemplate_Read","Product").Type(HttpVerbs.Get))

    )        
    .Scrollable()
)

Controller

 [HttpGet]

        public ActionResult RowTemplate_Read([DataSourceRequest] DataSourceRequest request)

        { 
            var productList = GetAllProduct().Select(e => new ProductListModel{Name = e.NameChi, Id = e.Id });


            return Json(productList.ToDataSourceResult(request));
        }

Here is the page and error view:

17-Nov-2013 Finally I find out the problem is DTO, I can not directly use it for binding, Anyone can tell me the reason?!

DTO CODE:

public class ProductDTO : DTO
    {

        [MaxLength(50)]
        public string NameChi { get; set; }

        [MaxLength(50)]
        public string NameEng { get; set; }

        public decimal Price { get; set; }

        public string DescriptionChi { get; set; }

        public string DescriptionEng { get; set; }

        public bool IsPublic { get; set; }

        [ForeignKey("Product_Brand")]
        public BrandDTO Brand { get; set; }

        [ForeignKey("Brand")]
        public int BrandId { get; private set; }

        public string MainPhotoPath { get; set; }

        [ForeignKey("ProductCategory")]
        public int ProductCategoryId { get; private set; }

        [ForeignKey("Product_ProductCategory")]
        public ProductCategoryDTO ProductCategory { get; set; }

        [ForeignKey("ProductType")]
        public int ProductTypeId { get; private set; }

        [ForeignKey("Product_ProductType")]
        public ProductTypeDTO ProductType { get; set; }

        public  List<PhotoDTO> PhotosPaths { get; set; }

        public  List<TagDTO> Tags { get; set; }
