demo code for custom filter doesn't appear to work

http://demos.kendoui.com/web/grid/filter-menu-customization.html

In your grid demo for filter menu customisation you define grid columns as follows:

@(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.EmployeeViewModel>()    
    .Name("Grid")
    .Columns(columns => {
        columns.Template(@<text>@item.FirstName  @item.LastName</text>)
                .ClientTemplate("#=FirstName# #=LastName#")
                .Title("Name");
        columns.Bound(e => e.City)
                .Filterable(filterable => filterable.UI("cityFilter"))
                .Width(200);

However, the Filterable method on a column only accepts a bool as an input value.
The code in this demo is not possible.
