Angular Material datepicker does not return value when action button is in use

Question

1. The problem is that when clicking today-button, it is working, but when changing the date in datepicker, nothing happens and this seems to be because action button is in use. How today-button is doable without action button?

2. If I add touchUi mode true, today-button disappears.

    <mat-form-field class="toolbar-button-calendar-picker">
      <input matInput [matDatepicker]="picker" #selDate (dateInput)="onDateChange($event.value)">
      <mat-datepicker class="date-picker" touchUi #picker>
        <mat-datepicker-actions>
            <button mat-raised-button color="primary"
              (click)="clickToDay.emit()"
              matDatepickerApply>
              {{ "today" | translate }}
            </button>
          </mat-datepicker-actions>
      </mat-datepicker>
    </mat-form-field>
