The code below throws a Javascript error that the function filter can not be found. Its defined right below the control. Why can't it be found?


                        @(Html.Kendo().ComboBoxFor(m=>m.childId)
                            .HtmlAttributes(new { style = "width:100%;" })
                            .Placeholder("Select ...")
                            .DataTextField("description")
                            .DataValueField("id")
                            .DataSource(source =>
                            {
                                source.Read(read =>
                                {
                                    read.Action("getData", "controller1")
                                    .Type(HttpVerbs.Get)
                                    .Data("filter");
                                })
                                .ServerFiltering(true);
                            })

                            .AutoBind(true)
                        )           
                        <script>
                            function filter() {
                                return {
                                    id: $("#Id").data("kendoComboBox").value()
                                }
                            }
                        </script>

Hi Kevin,

Getting this exception indicates the component is initialized in a partial view. In such cases the handler must be declared before the component's initialization, so try moving the script block with the "filter" handler before the ComboBox.
