Grid custom Editor template

[Denis]

I've done a custom template.

On edit mode, the model is not bind for Html.DisplayFor method.
Html.EditorFor works ans binds dynamically

What should i do to access to the data model ?
@Model is not bind

Thanks a lot for your help

=============== MyForm ==============
@model TestTelerik.Models.MyData

<h1>Ma custom form</h1>
data is @Html.DisplayFor(m => m.ProductName)

==========================================
@(Html.Telerik().Grid<TestTelerik.Models.MyData>()
     .Name("MyData")
     .ToolBar(command => command.Insert().ButtonType(GridButtonType.ImageAndText))
     .DataKeys(keys => keys.Add(p => p.ProductID))
     .DataBinding(dataBinding => dataBinding.Ajax()
        .Insert("AddNew", "Home")
        .Update("Update", "Home")
        .Select("Select", "Home"))
     .Columns(columns => {
         columns.Bound(p => p.ProductID).Width(50);
         columns.Bound(p => p.ProductName).Width(200); ;
         columns.Command(commands => { commands.Edit(); }).Width(50);
     })
     .Editable(editing => editing.Mode(GridEditMode.InForm).TemplateName("MyForm"))
)

============ Controller ============
public class HomeController : Controller
{
    public ActionResult Index()
    {
 return View(MyData.g_datas);

    }

[GridAction]

public ActionResult Select()
{
 return View(new GridModel(MyData .g_datas));
}

[AcceptVerbs(HttpVerbs.Post)]
[GridAction]
public ActionResult AddNew(MyData oData)
{
 if (ModelState.IsValid)
 {
  MyData.g_datas.Add(new MyData () { ProductID = oData.ProductID, ProductName = oData.ProductName });
 }
 return View(new GridModel(MyData.g_datas));
}

[AcceptVerbs(HttpVerbs.Post)]
[GridAction]
public ActionResult Update(MyData oData)
{
    return View(new GridModel(MyData .g_datas));
}
}
=========== MODEL ======================

[Serializable]

public class MyData
{
public int ProductID { get; set ; }

[Required ]
[DataType(DataType .Text)]
public String ProductName {get ; set ;}


public static List<MyData> g_datas = new List<MyData>{
 new MyData() {ProductID = 1, ProductName = "magic product" },
 new MyData() {ProductID = 2, ProductName = "super product" }};

}
