  Bug 28445: Adjust code to handle regexs

The problem is that the cataloguing plugins inject JS code in the DOM BEFORE the footer
in somes page we have all the JS loaded at the end of the DOM
and so $ (jQuery) is not defined

It's working on additem as we don't have the JS in the footer, but the
batch item mod tool has it there.

Test plan:
Batch edit items and confirm that cataloguing are working correctly with
this patch applied.
