I'm trying to use your directive to include a mvc partial view in my angular. But it doesn't work with Angular 10. Any Idea what's wrong?

inside the dynamic html you can pass an event trigger string back to the parent component to throw into a switch in order to control the behaviour
inside the dynamic html use
(click)="genEmit('pass back to parent')
inside the parent that holds the outlet
you can capture the emitted event
<html-outlet [html]="tableHTMLOutput" (genericEmitter)="captureEvent($event)" ></html-outlet>
