How does $ .ajaxError work?

I use $ .get, $ .post and $ .getJSON extensively, so I wanted to see how .ajaxError works. I tried this ...

$(document).ajaxError(function (e, xhr, options, error)
{
    console.log(e);
    console.log(xhr);
    console.log(options);
    console.log(error);
});

and I also tried to put it in mine $(document).ready().. And then I disconnected the network connection. AJAX made a lot of errors POST(because they received unexpected answers), and GETreturned instantly (cached), but nothing appeared in Firebug, as if ajaxError had never been called, What am I doing wrong? I just tried again without console logs and simply alert('foo'), and again nothing happened. Many errors, but ajaxError never fires.

If the ajax call made is a cross-domain, ajaxError is not triggered when the call fails.
