(ngModelChange) works fine without adding [ngModel]?

Question

I used ngModelChange without ngModel in an input in a form , it works fine , it's not supposed to work though, any explanation ?

the code

i expected it won't work without the ngModel but it works fine

Answer 1

You are using the formControlName Directive

It has a @Output('ngModelChange') update: EventEmitter but its marked as deprecated since v6 so there is a chance it wont work with the next updateds.
