DropDownList editor in a Form component with ServerFiltering enabled causes a js exception.

Reproduction of the problem

1. Enable ServerFiltering in the DropDownList editor:

@(Html.Kendo().Form<MVCFormValidation.Models.UserViewModel>()
	.Name("formExample")
	.HtmlAttributes(new { action = "/Home/Index", method = "POST" })
	.Validatable(v =>
	{
		v.ValidateOnBlur(true);
		v.ValidationSummary(vs => vs.Enable(false));
	})
	.Items(items =>
	{
		items.AddGroup()
			.Label("Registration Form")
			.Items(i =>
			{

				i.Add()
					.Field(f => f.FirstName)
					.Label(l => l.Text("First Name:"));

				i.Add()
					.Field(f => f.LastName)
					.Label(l => l.Text("Last Name:"));

				i.Add()
					.Field(f => f.NumberOfShares)
					.Label(l => l.Text("Number Of Shares:"));

				i.Add().Field(m => m.Country.Id)
					.Editor(e => e.DropDownList().DataSource(source =>
					{
						source.Read(read =>
						{
							read.Action("GetCountries", "Home");		
						})
						.ServerFiltering(true);
					}).Filter(FilterType.Contains).DataTextField("Name").DataValueField("Id"))
					.Label("Country");

				i.Add()
					.Field(f => f.Email)
					.Label(l => l.Text("Email:"));
				i.Add()
					.Field(f => f.DateOfBirth)
					.Label(l => l.Text("Date of Birth:").Optional(true));
				i.Add()
					.Field(f => f.Agree)
