how to reorganize with twig a form builded in a custom module and keep working ajax callback?
The solution for this case was just to add {{ form|without('global') }} at the end of the .twig file, like this :

&lt;div&gt;
  {{ form.global.info }}
  {{ form.global.controls }}
  {{ form.global.description }}
&lt;/div&gt;
{{ form|without('global') }}
