Angular material Datepicker get value on change

Sorry I didn't post the answer before, but I solved the problem with the @AJT_82's comment. Here is the code:

Component HTML

  <mat-form-field>
    <input matInput [matDatepicker]="picker" placeholder="Choose a date" [(ngModel)]="roomsFilter.date">
    <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
    <mat-datepicker #picker [(ngModel)]="roomsFilter.date" ngDefaultControl (selectedChanged)="onDate($event)"></mat-datepicker>
  </mat-form-field>

compoment ts

  public onDate(event): void {
    this.roomsFilter.date = event;
    this.getData(this.roomsFilter.date);
  }

Basically, I just passed the $event of the datepicker to get the value.

<mat-form-field>
  <input matInput [matDatepicker]="expiration1" placeholder="Expiration" [formControl]="expiration" required (dateChange)="EndDateChange($event)">
  <mat-datepicker-toggle matSuffix [for]="expiration1"></mat-datepicker-toggle>
  <mat-datepicker #expiration1></mat-datepicker>
</mat-form-field>
