Kendo MultiSelect Cannot read property 'value'
<p>It is my PartialView:</p>

<pre><code>.......

        &lt;div class="form-group"&gt;
            @Html.LabelFor(model =&gt; model.securities, htmlAttributes: new { @class = "control-label col-md-2"})
            &lt;div class="col-md-10"&gt;

       @(Html.Kendo().MultiSelect()
         .Name("productMultiSelect")
         .DataTextField("label")
         .DataValueField("value")Product to be used by the multiselect as a value.
         .HtmlAttributes(new { style = "width:350px; height:350px", @id = "prd" })
         .Filter(FilterType.Contains)
        .DataSource(source =&gt;
         {
             source.Read(read =&gt;
             {
                 read.Action("GetLogin", "IT_Inventory");
             })
             .ServerFiltering(false);
         })
        .Value(ViewBag.SelectedItem2)
        .ItemTemplate("&lt;span&gt;&lt;h3 style=\"font-size: 1.2em;font-weight: normal;margin: 0 0 1px 0;padding: 0;\"&gt;#: data.label #&lt;/h3&gt;&lt;p style=\"margin:0;padding:0;font-size: .8em; \"&gt;#: data.desc #&lt;/p&gt;&lt;/span&gt;")  
                )
            &lt;/div&gt;
        &lt;/div&gt;
</code></pre>

<p>My button:</p>

<pre><code>&lt;button type="button" id="btnSave" class="btn btn-success btn-lg"&gt;Save &lt;/button&gt;
</code></pre>

<p>My JS:</p>

<pre><code>&lt;script&gt;
    $("#btnSave").click(function (e) {
        e.preventdefault();
        $.ajax({
            type: 'POST',
            url: '@Url.Action("SignIT", "IT_Inventory")',
            data: JSON.stringify({ productMultiSelect: $("#productMultiSelect").data("kendoMultiSelect").value(), id: $("#id").val(), SomeBooleanProperty: false }),
            dataType: 'json',
            contentType: 'application/json',
            success: function (data) {
                if (data == true) {
                    $("#onInsert").data("kendoWindow").close();
                }
                else {
                    alert("Error!");
                }
            },
            error: function () {
                alert("An error has occured!!!");
            }
        });
    });
&lt;/script&gt;
</code></pre>

<p>When I try post to controller I am getting <code>Uncaught TypeError: Cannot read property 'value' of undefined</code>. For id and SomeBooleanProperty is ok.
When I use submit form is ok.
I should post data to controller list of productMultiSelect?</p>
