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" />


by



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


or



 <input type="checkbox" name="checkbox-i" #test 
 (ngModelChange)="clickOn($event)" [(ngModel)]="test.fav" />
