here is my hostlistener in the directive:

@HostListener(\'input\', [\'$event

If you wish to use a key code (or "which"), you can do this:

// @HostListener('document:keypress')

const escapeEvent: any = document.createEvent('CustomEvent');
escapeEvent.which = 27;
escapeEvent.initEvent('keypress', true, true);
document.dispatchEvent(escapeEvent);
