Kendo Grid simple ajax binding and sorting

Question

The error that i have received when tried to sort the Kendo grid by clicking on the Customer ID column is: {"Invalid property or field - 'CustomerID' for type: OMS_CUSTOMER"}. What else is needed to bind the columns of grid, model view and model. Thanks

controller _read function:

            IQueryable<OMS_CUSTOMER> CustomerList = this.dbContext.OMS_CUSTOMERs;

            DataSourceResult result = CustomerList.ToDataSourceResult(request
                , ModelState
                , c => new CustomerViewModel
                {
                    CustomerID = c.OMS_CUSTOMER_ID,
                    CustomerName = c.CUSTOMERNAME
                });

            return Json(result);

View:

        @model IEnumerable<NCBA.ViewModels.CustomerViewModel>

        @(Html.Kendo().Grid<NCBA.ViewModels.CustomerViewModel>()
            .Name("grid-CustomerViewModel")
            .DataSource(dataSource => dataSource
                .Ajax()
                .Model(
                        model =>
                        {
                            model.Id(cust => cust.CustomerID);
                        }
                )
                .Create(create => create.Action("_Create", "Customer"))
                .Read(read => read.Action("_Read", "Customer"))
                .Update(update => update.Action("_Update", "Customer"))
                .Destroy(destroy => destroy.Action("_Delete", "Customer"))
            )
            .Columns(columns =>
            {
                columns.Bound(c => c.CustomerID);
                columns.Bound(c => c.CustomerName);
                columns.Command(commands =>
                {
                    commands.Edit();
                    commands.Destroy();
                }).Title("Commands").Width(200);
            })
            .ToolBar(toolbar => toolbar.Create())
            .Editable(editable => editable.Mode(GridEditMode.InLine))
            .Pageable()
            .Sortable()
        )
