使用Angularjs更改多选元素

Question

我的页面中有一个多选元素。

 $scope.MainWinnerFilterSelected = @Html.Raw(Json.Encode(Model.SelectedWinner));

我可以先用下面的代码加载

 $scope.loadReasonAndWinner= function() {
        var productGroupFilters=$scope.productGroupFilterSelected;
        var res = $http.post('@Url.Action("GetWinnerAndReasonList", "Details")', {'selectedProductGroup':productGroupFilters});
        res.success(function(data, status) {
            $scope.MainWinnerFilters=data.WinnerList;
            $scope.MainReasonFilters=data.NotInterestingReasonList;
        });
        res.error(function(data, status) {
            $scope.addError("alert-danger","Bir Hata oluştu.","Error");
        });

    }

我想用新数据重新加载这个元素，但它很有效。

    [HttpPost]
    public ActionResult GetWinnerAndReasonList(int SelectedProductGroup)
    {
        var detail = new DetailsModel();
        detail.SelectedProductGroup = SelectedProductGroup;
        var winnerList = BiddingService.RetrieveWinners(null, VariableHelper.ListOf(detail.SelectedProductGroup));
        detail.WinnerList = BiddingService.TranslateToFilter(winnerList);

        var notInterestedActionStatus = new List<int>() { VariableHelper.Int(ActionStates.NotInterested) };
        var notInterestingReasonList = BiddingService.RetrieveActionReason(notInterestedActionStatus, VariableHelper.ListOf(detail.SelectedProductGroup));
        detail.NotInterestingReasonList = BiddingService.TranslateToFilter(notInterestingReasonList);

        return Json(detail);
    }

在控制器中;

新数据实现并且它与combobox（MainReasonFilter）一起使用，但它更改了多选元素（MainWinnerFilter）中的项目。有什么想法？
