Kendo网格下拉菜单的初始值未保存

Question

我正在使用像这样的几个自定义编辑器

function checkListEditor(container, options) {
    $('<input required data-text-field="Name" data-value-field="Id" data-bind="value:CheckListId"/>')
        .appendTo(container)
        .kendoDropDownList({
            autoBind: false,
            dataTextField: "Name",
            dataValueField: "Id",
            dataSource: {
                transport: {
                    read: '@Url.Action("GetCheckLists", "CheckList")',
                    dataType: "json"
                }
            },
            change: function (e) {
                var dataItem = this.dataItem(e.item);
                options.model.set("CheckListName", dataItem.Name);
            }
        });
}

我正在从db获取dataSource。更新工作没有问题，但创建却没有。预先选择的值有误。当我离开它时，它变成空的。如何解决？所有编辑器中都存在该问题。当我从下拉列表中选择其他值时，所有工作都会如预期

                                dataSource: {
                                    type: "json",
                                    transport: {
