Not able to get state changed value in other components angular with @ngrx/component-store

import { IStorageRoom } from '../models/storageRoom/storageRoom';
import { Injectable } from '@angular/core';
import { ComponentStore } from '@ngrx/component-store';
import { Observable } from 'rxjs';

export interface AddReservationState {
StorageRooms: IStorageRoom[];
storagetestId: any;
}
@Injectable()
export class ReservationStore extends ComponentStore<AddReservationState> {
constructor() {
super({
StorageRooms: [],
storagetestId: 'initial value',
});
}

StorageRooms$: Observable<IStorageRoom[]> = this.select(
(state) => state.StorageRooms
);
storagetestId$: Observable<any> = this.select((state) => state.storagetestId);
}


import { ReservationStore } from 'src/app/Store/AddReservation.store';

@Component({
selector: 'app-new-booking-modal',
templateUrl: './new-booking-modal.page.html',
styleUrls: ['./new-booking-modal.page.scss'],
providers: [ReservationStore],
})
export class NewBookingModalPage implements OnInit {
storagetestId$ = this.reservationStore.storagetestId$;
constructor(private reservationStore: ReservationStore) {}
ngOnInit() {
this.bookingFun(' changed value');
}
bookingFun(storagetestId) {
this.reservationStore.patchState({ storagetestId });
}
}
