Versions not changing when I try to update the model

[jayzyaj]

I tried to update my model and the version remains the same when I try to call the previousVersion() it returns me null and when I call the versions property it always return the same version.

Sorry if I misuse your plugin or boilerplate. I am just new in using your boilerplate or plugin. Or could you give me some real examples on how to use it. I gotta be honest that I didn't understand the examples in the documentation.
