ItemComparator function doesn't work if you set groupComparator function

[willianbrun]

Description
I was setting the groupComparator function, to separate my elements by date, and also setting the ItemComparator function, to sort it inside each group (by date too), but the itemComparator function was not working, in fact, the code isn't even executed.

Expected behavior
ItemComparator function sort the elements inside the group previously sorted.

Workaround
Set only the itemComparator function, and so, order group by ASC/DESC.

@Dimibe any updates?
Also, I noticed, that you made a lot of changes, but the latest release was 20 months ago. Can you release a new version, please?
