It took me a a couple of frustrating debuggin sessions to find out what was wrong with the code in Page 290-291. It might be obvious to most of the readers, but it might just help someone.
Although the code references to /Scripts/jquery-form.
js, the default MVC template does not contain the jquery-form.
js file. Hence, you will need to download the file from
here and put the script file inside Scripts folder.
Cheeers,
