Verint Community 12 Permission issue

Hi,

Here we trying to update permissions for registered users, even we set permission, that is not reflected any where.

it is working fine in version 11, we trying to do the same for version 12 , also followed the document given below

Defining Permissions - Developer Training - Verint Community 12.x - Verint | Telligent Community

But permissions not applied to the user.

In the given image I am updating Create permission for an application user, But that is not reflected. 

as per document its guided to use content type as " ContentTypes.GenericContent," image given below

But there is now such member in the contenttype class its version : 12

Kindly help us to fix this issue and implement permission.

Thanks in advance.
