Grid 剑道UI网格Aurelia的更新/删除事件

未触发更新/创建/删除事件。有什么想法吗

视图：

  <ak-grid k-option.bind = "gridOptions" id="adminGrid"  k-toolbar.bind="['create']" k-editable.bind="true"  k-pageable.bind="true" k-sortable.bind="true">
                       </ak-grid>

  activate(params) {
        this.name = params.type.toUpperCase();

        return this.getData(this.getType(), null).then(items => {

            this.getMetadata(items)
                .then(metadata => {
                    this.gridOptions = metadata;
                });
        });


    }
     getMetadata(items) {
            return new Promise(resolve => {
                resolve({
                    columns: this.getColumns(items),
                    autoSync: true,
                    dataSource: {
                        transport: {
                            read: //alert("read"),
                            function (e) {
                                e.success(items);
                            },
                            update:
                            function (e) {

                                }
                                return options;
                            }
