Hook to add value to field when page is added

[flash]

$wire->addHookAfter('Pages::added(template=booking)', function(HookEvent $event) {
        
$page = $event->arguments(0);
        
$selectable_pages = $page->getInputfield('booking_group')->getSelectablePages($page);    
   
$current_group = $selectable_pages->find("template=booking_price, parent.booking_current_group=1"); 
    
$first = $current_group->eq(0);
$second = $current_group->eq(1);
    
if ($page->booking_numberofpeople->id == 1 ) {
$page->setAndSave('booking_group', $first);
} 
        
    else if ($page->booking_numberofpeople->id !== 1 ) {
	$page->setAndSave('booking_group', $second);
    } 
   
    });

I have this code in ready.php

It works when i change to (Pages::save) but when (Pages::added) it doesn´t work? It sets the value to $second regardless..  Any clues?

booking_group = page reference field

booking_numberofpeople = select option field

the options in booking_numberofpeople is

1=1

2=2

3=3

4=4

5=5

Also i have set the required value to 1.

The pages are created from the module (Simple Contact Form).

 

Please help!!
