Bug 14794: Display JS tooltip whenever dateofbirth is being searched

This updates the code that adds a tooltip for the correct date format
to display after the initial search

To test:
1 - Do a patron search, choosing date of birth as the search field
2 - Note on choosing that field you get a tooltip defining the format
3 - Do a search
4 - Note tooltip is gone, but date fo birth is still selected as the field to search
5 - Apply patch, reload
6 - Note tooltip shows after initial search and until field is changed
