Bind DropDownList to action?

[Max]

Hello,

I have an Editor Template in which only a DropDownList is present. I am trying to populate that DropDownList using an action on my controller. I have the following code:

@(Html.Kendo().DropDownListFor(m => m)

                .DataSource(

                    datasource => datasource

                        .Read(r => r.Action("GetPossibleLines", "ProductionProgram"))

                        .ServerFiltering(true)

                    )

                .DataTextField("Text")

                .DataValueField("Value")

                .HtmlAttributes(new { style = "width: 200px" }))

My action looks like this:

[HttpPost]

public ActionResult GetPossibleLines()

{

    var options =

        new List<SelectListItem>()

        {

            new SelectListItem() { Text = "LI50", Value = "51" }

        };

 

    return Json(options);

}

What am I doing wrong? The DropDownList doesn't get filled and keeps loading forever.
