Javascript 将模板添加为innerHTML时Angular 2绑定/事件不起作用

我试图创建一个可配置的可重用表。可以将单元格配置为具有html模板

我正在配置列“Review”以使html模板具有带有click事件（Review（row））的锚定标记

到目前为止，我尝试将此模板作为innerHTML插入，但没有任何角度绑定可以工作。然后我尝试创建一个动态调用的组件（review.component.ts），但是这个组件在第一行只调用了一次。此外，我没有找到任何方法将当前行项目传递给单击EventReview（行）（inside review.component.ts）

employee.component.ts:

Angular不会以任何方式处理使用

innerHtml

（也可以是

ElementRef.nativeElement.append（…）

或类似方式）添加的HTML

如注释中所述，另一种方法是将HTML包装在组件中并动态添加此组件

DynamicComponentLoader

（如问题注释中的链接答案所示）已被弃用。它被替换为

ViewContainerRef.createComponent（）

。显示了如何使用它的示例。

这可能会有所帮助，
