asp.net mvc - ASP MVC and jsonp -

i need send data through jsonp response mvc application. jsonp response method used jsonpfilter.

this jsonp response method:

[jsonpfilter]     public jsonresult getpagename()     {         return new jsonresult         {             data = session["page"],             jsonrequestbehavior = jsonrequestbehavior.allowget         };     } 

and javascript function:

$.ajax({             type: "get",             datatype: "jsonp",             url: 'http://localhost:54845/login/getpagename',             contenttype: "application/json; charset=utf-8",             success: function (data) {                 alert(data.width + "-" + data.height);             }         }); 

this code works great on ff. in ie nothing happening.

what wrong in code? thank you.

are planning on making cross-domain http gets of json data? if not, why bother jsonp? use json.
