A possible solution is to request the fees history from the server using jQuery AJAX
when the edit
event is fired. This way the ancillary data will by accessible within the popup window.
In case the additional data is requested with the current page, another solution is to store the data inside a hidden input and retrieve it when edit
event is fired using jQuery.
Since there is no built in functionality for passing additional data to the edit popup window, please give a try to the aforementioned approaches and let me know if they work for you.
