Angular 4将ngModule对象传递给组件

Question

我正在尝试遵循https://blog.thoughtram.io/angular/2016/07/27/custom-form-controls-in-angular-2.html，它说明了如何将ngModel传递给组件。但是，当我传递模型对象时，它给我“无法分配给引用或变量！”错误。请帮帮我。 我的JSON对象是 [     {

        }            
    ]
}

我的组件HTML是

<form #form="ngForm">
    <div *ngFor="let coll of retroInfo[0].MyCollection">
        <div>{{coll.Name}}[{{coll.TotalPoints}}]</div>
        <div *ngFor="let pnt of coll.Points">
            <cal-field *ngIf="pnt.CalculatedField" [(ngModel)]="pnt" [ngModelOptions]="{standalone: true}"></cal-field>
            <non-cal-field *ngIf="!dp.CalculatedField"></non-cal-field>
        </div>
    </div> 
</form>

我需要构建如下表格
