当禁用另一个复选框时，kendo MVVM复选框会自动解除绑定

Question

模型是对象阵列。下面是我要检查的OnClick事件代码，取消选中基于PNR属性的其他复选框。如果相同的PNR复选框保持'ENABLED'，否则'DISABLED'。我正在使用Kendo MVVM。

  HTML code:
<td><input type="checkbox" data-bind="checked: IsSelected ,events: {click: OnTicketTstCheck},disabled: IsDisabled" /> </td>

script code:


    function OnTicketTSTCheckProcess(e) {
                debugger;
                if ($(e.target).prop("checked") == true) {

                    var element = e.target;
                    var PNR = e.target.kendoBindingTarget.source.Pnr;
                    $.each(TicketviewModel.TicketVMList,
                        function(i, v) {
                            debugger;
                            if (v.Pnr == PNR) {
                                v.set("IsDisabled", false);
                            } else {
                                v.set("IsDisabled", true);       
                            }
                        });

                } 
                else {
                    var anyChecked = false;
                    var PNR = $(e.target).closest(".TicketItem").find(".pnr").text();
                    $.each(TicketviewModel.TicketVMList,
                        function(i, v) {
                            debugger;
                            if (v.IsSelected == true) {
                                anyChecked = true;
                            }
                        });


                    if (anyChecked == false) {
                        $.each(TicketviewModel.TicketVMList,
                            function(i, v) {
                                debugger;
                                v.set("IsDisabled", false);
                            });
                    }

                }
            }

当下面的行被执行时 v.set（“IsDisabled”，true）;
  取消选中所选复选框
