Change how some methods are documented.

[MarkFChavez]

Description

While trying to learn the API, I found that some methods were not written exactly the way it should be. Is there something I'm missing here?

Changes

• Instead of call, use self.call
• Use self.actions instead of actions

BTW, I find this library useful and I've used it for a number of projects I'm working on. Keep up the good work!

Thank you so much for this PR! I am glad the documentation is getting better.
