Hi all, i need some help. (licensed version)

what I imagine:

I have a virtual column "remaining time" in the format h:m:s, on doubleclick the edit mode is activated and the cell change with my custom html code.
The custom html code include 3 textbox (hour, minute, second) and 3 button (add, cancel, sub).

I need some help to:
– Change the cell html with my own html code only on edit mode.
– Manage the "Add" "Cancel" "Sub" events relative to the selected row

Thanks
