Kendo Grid not calling correct DynamicLINQ method

My grid won't call my parameterized DataSourceResult methods. It just calls the parameterless one. I've studied this article till my eyes are falling out. What am I missing?

From my javascript controller:

$("#grid").kendoGrid({
    dataSource: {
        transport: {
            read: function (options) {
                userService.getGridUserList($.extend(options.data))
                .success(function (result) { options.success(result); })
                .error(function (result) { options.error(result); });
            },
            parameterMap: function(options, type) {
                return kendo.stringify(options);
            }
        },
        requestStart: function (e) {
        },
        requestEnd: function (e) {
        },
        schema: {
            data: "data",
            total: "total"
        },
        pageSize: 25,
        serverPaging: true,
        serverSorting: true,
        serverFiltering: true
    },
    height: 600,
    filterable: true,
    sortable: true,
    pageable: true,
    columns: [
        { field: "firstName", title: "First Name" },
        { field: "lastName", title: "Last Name" },
        { field: "email", title: "email" }
    ]
});

From my C# WebAPI:

//**doesn't get called**
public DataSourceResult GetGridUserList(GetUserGridListInput input)
{
    var q = repository.GetAll().OrderBy(t => t.Id);
    return q.ToDataSourceResult(input.Take, input.Skip. input.Sort, input.Filter);
}

//**doesn't get called**
public DataSourceResult GetGridUserList(int take, int skip, IEnumerable<Sort> sort, Filter filter)
{
    var q = repository.GetAll().OrderBy(t => t.Id);
    return q.ToDataSourceResult(take, skip, sort, filter);
}

//**gets called every time**
public DataSourceResult GetGridUserList()
{
    var q = repository.GetAll().OrderBy(t => t.Id);
    return  q.ToDataSourceResult(500, 0, null, null);
}

Turns out I was clobbering the grid parameters in my service call. What I needed to fix it, is to add {} as the first parameter:

userService.getGridUserList({}, $.extend(options.data))

The example uses a POST request, perhaps the grid requires that.

"I'm using a POST since MVC blocks unsecured GETS by default. That's good since we're going to be needing a POST request structure coming up shortly."
