jquery code :

<script type="text/javascript">
$(function(){
    $.ajax({
        url: "http://www.site.com/index.php",
        type: "POST",

}
echo $_GET['callback'] . '('. json_encode($data) . ')';
?>

post back:

({"success":false,"message":'ERROR ...'})

JSONP works by injecting a <script> element with a src attribute into a document.

That can only ever make a GET request.
