Pulling Parent Fields via Populate List

Question

Hi all. 
 I am trying to use the vardef (populate_list) to pull fields in on the subpanel create. I have this working for Contacts by doing something simple such as: 
 $dictionary['Contact']['fields']['account_name']['populate_list']['description'] = 'description'; 
 However when trying to do the same for a parent field (flex relate), I can't seem to pull it in. Even when using the actual link itself, for example: 
 $dictionary['Calls']['fields']['calls_leads']['populate_list']['description'] = 'description'; 
 I spotted the article from André Lopes ( https://sugarclub.sugarcrm.com/dev-club/b/dev-blog/posts/introducing-populate_5f00_list-in-parent-fields ) however when trying to implement it, nothing seems to be pulling, I've tried the following: 
 $dictionary["Calls"]["fields"]["parent_name"]['auto_populate'] = true;
$dictionary["Calls"]["fields"]["parent_name"]['parent_populate_list'] = [
	'Leads' => [
 'description' => 'description',
	]
];
$dictionary["Calls"]["fields"]["calls_leads"]['auto_populate'] = true;
$dictionary["Calls"]["fields"]["calls_leads"]['parent_populate_list'] = [
	'Leads' => [
 'description' => 'description',
	]
];
$dictionary["Calls"]["fields"]["calls_leads"]['auto_populate'] = true;
$dictionary["Calls"]["fields"]["calls_leads"]['parent_populate_list'] = [
	'leads' => [
 'description' => 'description',
	]
]; 
 I feel I am missing something super obvious, so if anyone can help I'd really appreciate it! 
 Thank you, 
 Daniel

Thank you for clarifications, Daniel. 
 Once you are creating Calls from subpanel under a Lead then you need to implement similar code into Leads as well: 
 $dictionary["Lead"]["fields"]["calls"]. 
 The code described in my article accomplishes creating/editing records directly from its module instead of creating a new one from subpanel.

Hi Daniel 
 
 The implementation I wrote in that article works like a charm in versions 9.x and 10.x. I still didn't try it under version 11.0. What is your current version? 
 Did you create custom js controller as per article instructions? 
 Mind that, as John Boyes noted, you should use bean name (Call) instead of module name (Calls). 
 John, parent_populate_list is the correct attribute, once my custom implementation on parent field type differs from core implementation. I implemented that way in order to avoid any further conflict.
