I guess removing the below line might resolve the issue.

jsonp:'jsoncallback',

try the following changes:

jsonpCallback: 'jsoncallback',
dataType: 'jsonp',
contentType: "application/json",

The way you used jsonp is wrong.Please check below mentioned link for more info.

$('document').ready(function() {
    var pm_url = 'http://twitter.com/status';
    pm_url += '/user_timeline/stephenfry.json';
    pm_url += '?count=10&callback=photos';
    $.ajax({
        url: pm_url,
        dataType: 'jsonp',
        jsonpCallback: 'photos',
        jsonp: 'callback',
    });
});
function photos (data) {
    alert(data);
    console.log(data);
};

Basic example of using .ajax() with JSONP

I hope this will help to you.
