my controller

public jsonresult updateuser(string customernameid, string userid, string umur, bool active)         {             var id = convert.toint32(userid);             var intumur = convert.toint32(umur);             var dd = db.datadiris.asqueryable().where(r => r.id == id).single();             dd.id = id;             dd.nama = customernameid;             dd.umur = intumur;              db.entry(dd).state = entitystate.modified;             db.savechanges();             string message = "success";             return json(message, jsonrequestbehavior.allowget);         }
