无法从KendoUI获取帖子值

Question

我遵循https://demos.telerik.com/kendo-ui/multiselect/addnewitem使用KendoUI Multi Select添加新项

控制器：

    [HttpPost]
    [Route("admin/blog/PostTag")]

    public IActionResult PostTag([FromForm]TagModel models)
    {            
        return Ok();
    }

模型总是获得空值，我也尝试不使用[FromForm] PostTag(TagModel models)或使用[FromBody]，但这是行不通的。

TagModel类：

public class TagModel
{
    public int Id     {get;set;}
    public string Tag { get; set; }
}

“查看”页面上的KendoUi：

 <select asp-for="Tag" data-placeholder="Chọn tag"></select>

                    <script id="noDataTemplate" type="text/x-kendo-tmpl">
                        # var value = instance.input.val(); #
                        # var id = instance.element[0].id; #
                        <div>
                            No data found. Do you want to add new item - '#: value #' ?
                        </div>
                        <br />
                        <button class="k-button" onclick="addNew('#: id #', '#: value #')" ontouchend="addNew('#: id #', '#: value #')">Add new item</button>
                    </script>
                    <script>
                        function addNew(widgetId, value) {
                            var widget = $("#" + widgetId).getKendoMultiSelect();
                            var dataSource = widget.dataSource;

                            if (confirm("Are you sure?")) {
                                dataSource.add({
                                    Id: 0,
                                    Tag: value
                                });
                                console.log(dataSource);
                                dataSource.sync();
                                //dataSource.one("requestEnd", function (args) {

                                //    if (args.type !== "create") {
                                //        return;
                                //    }
                                //     console.log(args.type)
                                //    var newValue = args.response[0].id;

                                //    dataSource.one("sync", function () {
                                //        widget.value(widget.value().concat([newValue]));
                                //    });
                                //});

                                //dataSource.sync();
                            }
                        }

我不知道为什么不能从Kendo捕获值，所以我改为从Request检索数据。
