[jQuery] getJSON invalid label

[jQuery] getJSON invalid label


What am I doing wrong? Im able to submit the request and get a
response, but in Firebug it says invalid label and the alert doesnt
show up.
here is my code:
$("form").submit(function() {
$.getJSON("http://api.nytimes.com/svc/movies/v2/reviews/
search.json?api-
key=c82338627fba39e9bcb953728fe445a2:15:57546791&callback=?", {query :
$('#query').val()}, function(data){
alert(data);
});
return false;
});
