No need to handle that signal is all you want is beeing able to control 
the sorting by clicking on the column headers, though. That is handled 
automatically by the TreeView once you activate sorting.

In addition, you may want to add a sort function on your date column 
with TreeSortable::set_sort_func(), as sorting will be done in 
"alphabetic" order, which, depending on your date format, may not be the 
order you want. Alternatively, store the date in numeric format and add 
a data_func to convert it into a string in which case the default 
sorting order would be what you want.
