Webform address killing ajax?

How do I attach an Ajax behavior to my country field (that already has a dropdown behavior).

I have a simple form defined using the webform module.

In an implementation of hook_webform_alter I have the following code that works...

$form['elements']['business_e_mail']['#ajax'] = [
    'callback' => 'ajax_callback',
    'wrapper' => 'opt-in-wrapper',
    'disable-refocus' => FALSE, 
    'event' => 'change',
  ];

However, if I attempt to attach the #ajax behavior to the country field which is really what I need, I get no response. (e.g., the ajax callback is not called)

Code that does not work

$form['elements']['country_code']['#ajax'] = [
    'callback' => 'ajax_callback',
    'wrapper' => 'opt-in-wrapper',
    'disable-refocus' => FALSE,
    'event' => 'change',
  ];

The only seemingly relevent difference between the two fields is that the working field is a simple email address.

The country_code is an address field that also has a behavior attached to it (e.g., it is a dropdown.

Any help would be much appreciated!

What does the unaltered `$form['elements']['country_code']` look like in the form definition? You may need to attach the `#ajax` to a child of that.

@jaypan Thanks for jumping into this one... The form is pretty much boilerplate from the webform module. ` country_code [ #type #title #webform_key #webform_plugin_id ... ` Interesting idea you've got... not sure how effective it will be because I need to find an element that changes - right?

I would need to find a child that is modified, or maybe not? `country_code [ #title #webform_key #country_code__options ]`

I don't use webform myself. But form elements in Drupal often have children form elements, and you need to attach the #ajax to the actual form element (select, input) as it won't work when attaching it to a parent. This indicates to me that you've attached it to a parent, not the child.
