Support InputSignal for ComponentRef

[Celtian]

Which @angular/* package(s) are relevant/related to the feature request?

No response

Description

Right now I am probably unable to pass InputSignal via ComponentRef

@Component({
  ...
})
export class TooltipComponent {
  public text = input.required<string>();
}

@Directive({
  selector: '[appTooltip]',
  standalone: true,
})
export class TooltipDirective {
  private overlay = inject(Overlay);

  private overlayRef = this.overlay.create({
    // positionStrategy: this.positionStrategy(),
  });

  public tooltipText = input.required<string>();

  @HostListener('mouseenter')
  public show(): void {
    const tooltipPortal = new ComponentPortal(TooltipComponent);
    const tooltipRef: ComponentRef<TooltipComponent> = this.overlayRef.attach(tooltipPortal);
    tooltipRef.instance.text = this.tooltipText; // <-- this is not working
  }
}

Proposed solution

This line should be working

tooltipRef.instance.text = this.tooltipText; 

Alternatives considered

Or it should work like

tooltipRef.instance.text = this.tooltipText(); 

[atscott]

This is expected. You should use ComponentRef.setInput instead. Directly assigning values in this way sidesteps the features of inputs (such as ngOnChanges or notifying Angular that change detection needs to run)
