How to set label for radio

I need to set labels for radio-buttons in my script.
For other controls I can use
dhxForm.setItemLabel(name, “New label”);
But this not works for radio button.
dhxForm v 2.6

this.setItemLabel = function(id, value, text)

Yes you are right.

With radioboxes you need to set additional attribute “label” right after “id”.
