Circumvent compose not being called by reactive variable change

[alexisthual]

Good evening!

First of all, thanks for the great library 😊

I am surprised that, in a custom Widget, a change in a reactive variable doesn't call compose() again.
Is there a way that, using compose(), I can refresh a widget (and it's children widgets) whose variable just got changed?
If not, can I achieve this without compose()?

My use case is the following: I am building an application with multiple nested widgets.
I want a change in one of the main variables of the application to refresh the whole app.
I chose to use compose() and not render() because I am mostly working with widgets and could not find a way to instantiate lists of widgets in render().

Thanks!

The way to think of it is compose builds the structure of your widget; you don't want to tear down and rebuild a structure every time. If you're using reactives the best thing to do with a compound widget that's build up with compose is to use the watch system and update the parts of the widget that require updating.

The documentation talking about compound widgets might be helpful here.
