Gem not working properly....converting PUT(update) call to POST

[rsk-07]

I created a simple rails app:
:~ rails generate scaffold User name:string email:string
:~ rake db:migrate
and then edited _form.html.erb for using the DataTable Plugin:

The form works completely well when a User is created. But, when i try update User's information it returns me a routing error:
No route matches [POST] "/users/1"

For Update the call should have been PUT but it is using POST here. It only happens when I use the Gem otherwise the Update is working fine.
Please look into the following matter.
