How to update the data on the page (backbone)?

Question

JavaScript

I'm new to backbone, tell me, please, I have 2 tags on the page, when you select any in one, the data should change in the second. I update the model, but the data in the second one does not change. How to update the data in the second select? and only in it, without redrawing the entire page. Thanks in advance.

Listen to events and models in the View and redraw what you need. Backbone is a pretty low-level thing, so it's all by hand.
