I didn't manage to set up a test case with jsfiddle but I manage to solve my issue by initialising the modal html structure with a placeholder bigger than the mobile screen height which seems to initialise properly the scroll bar and the correct focus on the modal when it will appear. So when showing the modal I call my ajax function as before but it replaces the placeholder content with the dynamic one.
I would prefer to find a more elegant way to solve this but it works.
