Sonata admin : list always use defaut language - symfony

Question

I use sonata admin bundle with Symfony 3.4 and knplabs. Everything work fine excepted one thing.
I have create a Test class and the sonata list with the CRUD.
This class has a translatable title, when I'm on the edit mode of one on my test object, I can click on the flag for editing the title in many languages.
But when I'm on my list view, the flag are display but when I click on it, the list always display the title in english (default language).
I debug and find that in edit view, method setLocale and getLocal are used to change the languages but in list view, they are not call.
How can I translate my entites in my list view ?
Here my test class, translation test class and my testAdmin.
Test.php
