Type casting within a template in Angular 2

Question

I\'m working on an Angular project (Angular 4.0.0) and I\'m having trouble binding a property of an abstract class to ngModel because I first need to cast it as the concrete

Answer 1

If you don't care about type control.

In Angular 8 and higher versions

[(ngModel)]="$any(event).acknowledged"
