Grid Grouping a DataSource is required to create Manager

[Aaron]

In my razor view I have the following       

@model IEnumerable<ObjectType>

@{

    Layout = "~/Views/Admin/_AdminLayout.cshtml";

}

<div class="containter">

    @(Html.EJ().Grid<ObjectType>("Details")

                .Datasource(ds => ds.Json(Model)

                            .UpdateURL("EditData")

                            .InsertURL("AddData")

                    .RemoveURL("NormalDelete")

                    .Adaptor(AdaptorType.RemoteSaveAdaptor))

    .AllowGrouping()

    .EnableHeaderHover()

    .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing(); })

              .ToolbarSettings(toolbar =>

                {

                    toolbar.ShowToolbar().ToolbarItems(items =>

                    {

                        items.AddTool(ToolBarItems.Add);

                        items.AddTool(ToolBarItems.Edit);

                        items.AddTool(ToolBarItems.Delete);

                        items.AddTool(ToolBarItems.Update);

                        items.AddTool(ToolBarItems.Cancel);

                    });

                })

    .AllowPaging()

    .AllowScrolling()

  //  .GroupSettings(group =>

 //   {

 //      group.GroupedColumns(col => { col.Add("1" }).EnableDropAreaAnimation(false);

//    })

    .Columns(col =>

    {

    col.Field("1").ToString())

    .HeaderText("1").ToString())

    .IsPrimaryKey(true)

    .TextAlign(TextAlign.Right)

    .Visible(false)

    .Add();

    col.Field("2").ToString())

    .HeaderText("2")

    .Add();

    col.Field("3")

    .HeaderText("3")

    .Add();

    col.Field("4")

    .HeaderText("4")

    .TextAlign(TextAlign.Right)

    .Add();

    col.Field("5")

    .HeaderText("5")

    .Add();

    col.Field("6")

    .HeaderText("6")

    .Add();

    })

    )

</div>

The  Page loads and the data is displayed.  Paging Works  and the Editing / Adding works as well.    But when I try to group the columns I get the following javascript error

ej.web.all.min.js:10 Uncaught DataManger : a dataSource is required to create Manager
