How to change the header of the ListGrid from javascript

I am using SmartClient_v111p_2017-07-03_LGPL in IE11.
I have not been able to determine how to change the Header text of a field in a listgrid. I have tried:

lg.header.buttons[0].title = (check ? 'Deselect All' : 'Select All');
lg.getFields()[0].title = (check ? 'Deselect All' : 'Select All');
lg.refreshCell(-1, 0);

The program detect the change, but the change is not displayed

listGrid.setFieldTitle() will do it...

That worked, I missed that function.
