Qt.Quick.Controls 1.4: Resize TableView Columns with doubleclick

[AlaNan]

When I doubleclick on a column separator in my TableView it is resized to fit the content but the header size is ignored. I think this is due to this bug.
I managed to implement a way to resize the columns of the table correctly and I use it whenever model data changes.
Now I want to use it on doubleclick too! I think I would just need to implement a handler for that very signal that calls my resize function. But I cannot find this signal in the documentation.

Does anybody know how to achieve what I'm trying to do?

Nobody? Really?
Ok.
Let me rephrase the question:
Is it possible to change the behavior of resizing on doubleclick on column separator for Table VIew in Qt.Quick.Controls 1 without changing the C++ implementation of Table View itself?
Yes or no?
Please, there must be someone who can answer this question m(-_-)m
