角度9 ng-select多选和反应形式

Question

我已将反应形式和ng-select连接起来，现在我可以很顺利地获得该值，但是当我尝试以任何方式修补该值均不起作用时，

在这里帮我

我尝试

    this.profileForm.patchValue({
      cuns: [{ID: 69}],

    });

    this.profileForm.controls['cuns'].setValue(69, {onlySelf: true});

还有更多，这是我的html

                  <ng-select [items]="this.allCits"
                    formControlName="cits"
                    [multiple]="true"
                    bindLabel="CityNameProfile1"
                    bindValue="ID">
                    <ng-template ng-label-tmp let-item="item">
                      <b>{{item.CityNameProfile1}}</b>
                    </ng-template>
                    <ng-template ng-option-tmp let-item="item" let-item$="item$" let-index="index">
                      <input id="item-{{index}}" type="checkbox" [ngModel]="item$.selected" [ngModelOptions]="{standalone: true}"/> {{item.CityNameProfile1}}
                    </ng-template>
                    <ng-template ng-option-tmp let-item="item" let-index="index" let-search="searchTerm">
                        <b [ngOptionHighlight]="search">{{item.CityNameProfile1}}</b>
                    </ng-template>
                  </ng-select>
