Hi everybody,
I have this:

 @using Multitask.Regenboog.Medicijnverstrekking.WebApplication.ViewModels.Medicijn
@{
ViewBag.Title = "Volgorde";
}
@section Head
{
@Styles.Render("~/content/kendo/style")
@Styles.Render("~/content/toastr")
}
<style>
.k-grid-filter.k-state-active {
background-color: #fff;
}
</style>
<div class="row">
<div class="col-md-8">
<h2>Medicijnen</h2>
</div>
</div>
<div id="grid"></div>
@(Html.Kendo().Grid<MedicijnVolgordeViewModel>()
.Name("medicijnenGridVolgorde")
.Columns(columns =>
{
columns.Bound(c => c.Id).Hidden().IncludeInMenu(false);
columns.Bound(c => c.Naam).Title("Naam").HtmlAttributes(new { @style = "width:400px;" }).Width(100);
columns.Bound(c => c.Volgorde).Title("Volgorde").Width(150);
})
.Sortable()
.Selectable(selectable => selectable
.Mode(GridSelectionMode.Single)
.Type(GridSelectionType.Row))

.Deferred()
)
<div style="margin-top: 10px;">
@Html.ActionLink("Toevoegen", "Create", "Medicijn", null, new { @class = "btn btn-success" })
</div>
@(Html.Kendo().Tooltip()
.For("#medicijnenGridVolgorde")

<script type="text/javascript">

var dataSource = new kendo.data.DataSource({
