webservice asmx example not working hosting area and no error (jquery datatables , asmx, AJAX,C#)

I found a basic webservice asmx example ( c# and sql stored prosedure jquery datatables and webservice) and applicated- called getstudent-
It works via Visualstudio publish and there is no problem when publising in my localhost.

Visual studio --> url : "StudentService.asmx/GetStudents" ok
localhost ---> url: "localhost/test/StudentService.asmx/GetStudents" ok

I tried several url like url: "http://www.myhost.com/StudentService.asmx/GetStudents",
but when publising in my hosting area (internet) there is no error , only shows the coulums.

I think there is a mistake StudentService.asmx 's url.

Please help me.
