Error with setTextFormat() method

Question

This is a very common issue but is still pissing me off.
I've this code:
item.addEventListener(MouseEvent.CLICK, function(e) {
            var style:TextFormat = new TextFormat();
            style.underline = true;
            e.currentTarget.label.text.setTextFormat(style);
Everytime I click on item I get back this error:
TypeError: Error #1006: value non è una funzione.
    at Function/<anonymous>()
Any ideas?

try:
item.addEventListener(MouseEvent.CLICK, function(e) {
            var style:TextFormat = new TextFormat();
            style.underline = true;
            e.currentTarget.label.setTextFormat(style);
