How to make a button active / inactive in the backbone depending on the condition?

Question

JavaScript

That is, there is a button on the page with the attribute 'disabled', you need to make it active after certain conditions are met, for example, form fields are filled and checkboxes are selected. Everything is simple in angular, just write ng-disabled="anyFunc()", but in backbone it's not so obvious.
