Bug 23202: Fix screen freeze when ordereing several items

This patch fixes adding multiple items on order acquisitions

The error is: Uncaught TypeError: $(...).parent(...).attr(...) is undefined

Test plan:
1) Set dateaccessioned.pl plugin to ACQ framework's 952$d field.
2) Create basket to a vendor and add order from a new empty record.
3) Add date acquired value from calendar.
4) Add multiple items and see that the view freezes.
5) Apply the patch
6) Reload the page and repeat the steps 3 and 4.
7) See that the items are added.
