Cannot read property 'value' of undefined

After installing msignal and react and running haxe build.hxml command within the sample Todo App directory.

I've received an error on the click function of the todo with the class.button-add.

TodoApp.hx:65 Uncaught TypeError: Cannot read property 'value' of undefined

Is this an issue with an outdated react bundle or the compiled JS?

The sample may have rotten... I'll try to review that asap.
