not sure. maybe you could ask the author of the Datatables plugin? To see what I'm getting at, do this:
1. reload the page
2. open your browser's console (firebug, chrome dev tools, etc.)
3. paste the following and then press Enter: oTable.find('a.tooltip').cluetip({local:true, cursor: 'pointer'});
Hovering over the page icons should show the tooltips.
4. change the number of items to show
hovering over the page icons will not show the tooltips
5. repeat step 3.
hovering over the page icons should show the tooltips.

It's just a matter now of figuring out where to include that call to .cluetip() from within a datatable callback.
One more thing: check out the error console. it looks like you're getting an error regarding an addMethod function ("Uncaught TypeError: Cannot call method 'addMethod' of undefined")
