Autocomplete with remote datasouce not showing Multicolumns

Hi,

I'm trying the Multicolumn settings in the Autocomplete Textbox, but it doesn't seem to work with remote datasource.  This is my control:

@{
        Html.EJ()
            .Autocomplete("searchCustomer")
            .Datasource(d => d.URL("http://mvc.syncfusion.com/Services/Northwnd.svc/").Offline(false))
            .Query("ej.Query().from('Suppliers').select('SupplierID', 'ContactName')")
            .AutocompleteFields(f => f.Text("ContactName").Key("SupplierID"))           
            .WatermarkText("Search a customer")
            .MultiColumnSettings(obj => obj.Enable(true)
                .Columns(obj1 =>
                {
                    obj1.Field("SupplierID").HeaderText("Id").Add();
                    obj1.Field("ContactName").HeaderText("Supplier").Add();
                })
                .ShowHeader(true)
                .StringFormat("{0} ({1})")
                )
            .Render();
    }

 Can anyone help? is it possible to use it with remote data?

Thanks
