ListView: NotSupportedException: "ClientTemplateId or ClientTemplateHandler" cannot be null or empty.

Hi,

after we've updated at the last version, listview component stop working.

Below the code snippet:

<script type="text/x-kendo-tmpl" id="groupConfigTemplate">
    <div >
        #:Name#
    </div>
</script><script>
    function filterLinkerGroup() {
        return {
            linkerGroupId: $("#ddlLinkerGroup").data('kendoDropDownList').value()
        }
    }
</script>

 @(Html.Kendo().ListView<LinkerConfigViewModel>()
                .Name("lvLinkerGroupConfig")
                .TagName("div")
                .ClientTemplateId("groupConfigTemplate")
                .DataSource(source =>
                {
                    source.Ajax().Read(read =>
                    {
                        read.Action("ReadLinkerGroupConfig", urlController).Data("filterLinkerGroup");
                    });
                })
                .AutoBind(false))
