Task: you want to rebuild the existing view or replace some component in it
Solution: use addView() of Webix views
addView is a Webix method of layout widgets like Form, MultiView, etc. You can use it to add Webix components to Jet views as well. Yet, it will work a little differently. The point is that addView uses regular webix.ui pattern of view initialization, which does not work with the Jet $scope. So, apart from the Webix view configuration that is usually passed to addView as a parameter, you must set $scope to this:
Have a look at the example. This is a Jet class view with a small Webix form:
Let's dynamically add a button and define a class method changeView for that. To reference the Webix form from the method, use this.getRoot(), where this is the Jet class view and getRoot returns the form.
