Can't Select Table Rows for New Rows Only

Hi, I've seen some discussions on here regarding this but not exactly matching my situation that I could find.

I'm adding new data to the table by using fnAddData() dynamically. The the new row of data is added correctly to the table, however I'm not able to select the row by clicking on it. All table rows that were not dynamically added are still selectable.

I have the following code that toggles the table rows if they are selected or not. Keep in mind I'm allowing for multiple rows to be selected.

Any suggestions on how to resolve this would be greatly appreciated as I can't seem to locate the issue. I've even tried placing an alert() within the click event below and the alert() is never executed when trying to click (select) on the dynamically added table rows.

$('#example tr').click( function() {
$(this).toggleClass('row_selected');
} );

Here is the code used for toggling selected table rows and the dynamic code that adds new data to the table.
