Как записать данные в массив?

<form [formGroup]="userListControl">
  <ul formArrayName="users">
    <li *ngFor="let userControl of userListControl.controls.users.controls; let i = index">
      <input formControlName="{{i}}">
      <button (click)="removeUserControl(i)">Remove</button>
    </li>
  </ul>
</form>
<button (click)="addUserControl()">Add User</button>

this.userListControl = this.formBuilder.group({
      users: this.formBuilder.array([ ['Jhon'], ['Alice'], ['Bob'] ])
    });
