Namespace Method as jsonp callback name

[chentsulin]

Is it possible to use namespace method as a jsonp callback name ?

With jQuery 1.11.1

var callback = function() {};
window.mynamespace = window.mynamespace || {};
window.mynamespace.callback = callback;

$.ajax({
     url: 'http://localhost:3000/',
     dataType: 'jsonp',
     jsonp: 'callback',
     jsonpCallback: 'mynamespace.callback',
     success: function() {
           alert('SUCCESS!');
     },
     error: function() {
          alert('ERROR!');
     }
});

After server respense, mynamespace.callback was called.
But get Error: mynamespace.callback was not called and alert Error.

Could I only use global function as jsonp callback name?

Support for this feature would mean adding relatively ugly and big amount of code with pretty little gain.

So no, sorry.
