My problem was with sharing_display and not Jetpack_Likes (my bad :/).

In Ajax context sharing_display return nothing because of this code :

if ( is_preview() || is_admin() ) {
		return $text;
	}

in /jetpack/modules/sharedaddy/sharing-service.php

I think that the is_admin() return true because of admin-ajax.php.

Thank’s for your reply.

It seems that the Jetpack_Likes isn’t loaded at all.
If I do “$custom_likes = new Jetpack_Likes;” without doing class_exists before I’ve got this error : “Fatal error: Class ‘Jetpack_Likes’ not found”.

I tried to require likes scripts :
require_once('../wp-content/plugins/jetpack/modules/likes.php');

With this, the error disappear, but the buttons don’t shows.
Maybe I must call some jetpack hooks …
