$.getJSON problem with json parameter


Hi.
I'm trying to use function $.getJSON with JSON parameter, but it not
work "100%".
i.e.:
$.getJSON( "<URL>", { parent: { child: value } }, callbackFunction );
, and my variable parent.child wasn't populated.
After these test i try to use only " { child: value } ", and then it
work corretly.
Why my first code not work? Any idea?
Thanks.
