Explanation :
when you are using jsonp as datatype (making cross domain request) Jquery generate random function and append is to requested url as a querystring named callback (callback=?), you need to append response json data as a parameter of this function as given below -

url : http://www.dotnetbull.com/cross-domain-call.ashx?ref=jquery-jsonp-request
url call by ajax :
http://www.dotnetbull.com/cross-domain-call.ashx?ref=jquery-jsonp-request&callback=jQuery1510993527567155793_137593181353

Response data should look like this :
jQuery1510993527567155793_137593181353( {  "result": "success", "ref": "jquery-jsonp-request" } )


string callback = context.Request.QueryString["callback"];

if (!string.IsNullOrEmpty(callback))
     context.Response.Write(string.Format("{0}({1});", callback, jc.Serialize(outputData)));
 else

     context.Response.Write(jc.Serialize(outputData));
