Ribbon Contextual Groups and Tabs in SharePoint

Question

I am new to SharePoint ribbon. Why do I not see the View and Edit buttons in the Manage group of my tab?

Here are my definitions for your reference:

Answer 1

Okay this is what I had to do:

1. Do not use _ (underscore) in the Id.
2. Change my layout to use OverflowSection
