can vim-binding fix the `esc` issue on ipad?

Summary

commands to leave normal mode, as well as those to leave insert mode, eg. Ctrl-[ suggested in #124 work fine for me on OS X browser. They do not work however on iPad browsers (Safari and Chrome). This seems to be an issue with the esc key not being there in iOS devices (see https://github.com/jupyter/notebook/issues/2378

I have installed vim-binding for Jupyter to fix my iOS issue. So far I am pretty happy with the vim-like experience I get on my mac, but it's so close to work on iPad that it's a real pity the esc button and all the possible substitutes I tried do not work.

Do you think jupyter-vim-binding can lead to a solution of this esc button issue on iOS?
