Do you mean it doesn't fire a ngModelChange event when value is false?

Or that it triggers initially, wihout any user action?

Use reference of checkbox element and pass the value or use ngModelChange

Replace the below code

<input type="checkbox" name="checkbox-{{i}}" (change)="clickOn(test.fav)" [(ngModel)]="test.fav" />

<input type="checkbox" name="checkbox-{{i}}" #test 

     (change)="clickOn(test.value)" [(ngModel)]="test.fav" />

 <input type="checkbox" name="checkbox-{{i}}" #test 

     (ngModelChange)="clickOn($event)" [(ngModel)]="test.fav" />
