Is there specific event for column header click?

I have custom server side pagination made for DataTable, because data is very big.
I need to somehow implement server side sorting for it now. The only thing I can think of is having callback for clicking the column header but I’m not sure it is possible.

There’s not currently any such event, IIRC because the underlying SlickGrid did not really expose anything we could hook into. But that was some time ago, so it might be worth another look to see if anything has changed. Feel free to raise a GitHub development discussion about this topic.
