If you are using "Partial Page Refresh" to navigate through the pages of a report, the new methods live and die should be useful.
Before, we were able to bind a click event to DOM elements. The click event was not propagating itself to new DOM elements created dynamically after the bind action.
For example: if you bind the click event to every rows of your report, you have to bind the click event to new rows generated after calling the function $a_report.
Now, we are able to bind a live event to our DOM elements. The click event is now able to propagate itself to new DOM elements created dynamically after the bind action.
You can try a working example of jQuery Event Live in APEX.
Happy Web 2.0 coding! :)
