Voila only works with Jupyter interactive widgets.  
`input()` is an old legacy thing from IPython and not really Jupyter, and so it won’t work in Voila.

See my recent mention of text collection more modern ways [here](https://discourse.jupyter.org/t/keyboard-shortcut-o-interfering-with-input/38205/4).
