Selgitage, mis on probleem ülaltoodud Angular komponendi koodiga ja kuidas seda parandada:
```typescript
@Component({
selector: 'app-user',
template: './user.component.html',
stylesUrls: './user.component.scs',
changeDetection: ChangeDetectionStrategy.OnPush,
})
export class CmfUserComponent {
users$: any;
constructor() {
const api = new BackendService();
this.users$ = api.getUsers();
}
}
```
