String variable doesn't rendered

Hello! I have a variable I wanna be reactive. Example is simple: user types in an email's input, value reactively renders on the page. But it doesn't happens :( Variable's value changed, but doesn't rendered. Example on codesandbox. Thank you!

In MobX v6 you should call makeObservable / makeAutoObservable, even with decorators.
