Answer 1

You cannot have [checked] bound to two different values, that will not work. A better solution is to set [checked] to "user" as you have done the second time, and then set user to true . So your code would change to

  <input type="checkbox" name="users" ngModel #users="ngModel"  id="users" [checked]="user"  onclick="if(users.checked) {pets.checked=false}"  required />

and then is ts, set user to be true when you define it

user = true
