How to add control logic to a plugin for Django-CMS?

Question

Django

Hello, I ran into a misunderstanding. After reading the manual django-cms.readthedocs.org/en/latest/how_to/custom... and creating an example https://jsfiddle.net/k5zmuf42/ based on it , I got a ready-made plugin. Now I want to add additional data processing to it, like in a view, or connect it myself, but unfortunately, I did not find how to do this.
Please, tell me where in the documentation it is written how this can be done.
PS From what I read, I learned how to connect models to the plugin and work with them accordingly (select, display), but, of course, more complex processing is required.
