我正在创建新的angular 2应用程序，其中分别创建了一个component（html和ts）文件。
我已经在其中显示了列表以及用于编辑和添加记录的列表模型。
现在，当我提交表单时，只有两个字段将正确的数据传递给组件。其余字段为空。另外，当我尝试编辑记录时，什么也没有发生。谁能帮助我解决问题。
这是我的模特。
export interface ProductCategory{
categoryId: number;
productType: string;
description : string;
updatedBy: Date;
isActive: boolean;
lastUpdatedDate: Date;
}
这是我的HTML组件。

除了列表以外，什么都没有。
以下是我第一次加载数据时的json。
[{"categoryId":1,"productType":"It product","description":"All product Related to IT","updatedBy":"It user2","isActive":true,"lastUpdatedDate":"2018-07-18T19:47:20.817"},{"categoryId":2,"productType":"Home product","description":"All product Related to Home","updatedBy":"Home user","isActive":true,"lastUpdatedDate":"2018-07-14T23:31:55.09"},{"categoryId":10002,"productType":"Sport user","description":"Sport user Category","updatedBy":"Sport user","isActive":true,"lastUpdatedDate":"2018-07-19T18:55:02"},{"categoryId":10005,"productType":"Caar User","description":"Caar User Category","updatedBy":"Caar User","isActive":true,"lastUpdatedDate":"2018-07-19T18:55:02"}]
请帮助我解决此问题。
预先感谢。 欧姆卡。
