AngularJs and jsonp not working - angularjs

Question

I have some problems with jsonp and AngularJs
I one page, i have to make about 15 json calls, each one by jsonp
My calls look like this :
$http.jsonp("http://www.example.com/feed1.json?callback=JSON_CALLBACK1")
And in my json feed, the data is wrapped by JSON_CALLBACK1
But i always obtain this error :
Uncaught ReferenceError: JSON_CALLBACK1 is not defined
Now i noticed in the network tab in the Google Chrome inspector that the call was :
http://www.example.com/feed1.json?callback=angular.callbacks._0
So i changed my json file, to wrap data with angular.callbacks._0(); instead, and it worked for this one, but it did not work for all my json
I started wraping all my jsons with angular.callbacks._1, angular.callbacks._2, angular.callbacks._3 ... byt i noticed that the number isn't always the same ? and if the number is a two digits, it doesn't work. For example, i tryed angular.callbacks._15, and i always obtain this error
Uncaught ReferenceError: angular.callbacks._15 is not defined
So is there a way to fix all those jsonp problems once for all with AngularJs ?
Thanks

The callback=angular.callbacks._123 parameter is an information for the server that the client (browser) expects the response to be wrapped inside a function named angular.callbacks._123 like so:
angular.callbacks._123({
"key": "value"
});
You should change your server code to inspect the parameter value and if present use it as the wrapping function name.
You can find more details in wikipedia.
