jquery_update needed to work properly

@lonalore what do you think about this? Any need for a change or documentation?

jQuery .on() was introduced in jQuery 1.6 or 1.7? If I remember well, Drupal 7 uses jQuery v1.4 by default.
In my opinion, the simplest solution would be if we remove the jQuery usage (inside the jQuery Once callback).
Essentially, only the D10 code needs to be backported.
