Detect changes on Rich Editor inputs field

[Loocos]

Hello,

I'm wondering how can we easly detect changes on rich editor fields because I want to implement this : https://plugins.jquery.com/are-you-sure/

After adding/removing any part of a rich editor field, I need to reload the hidden input field in order to make the "Are you sure" working well.

Can we handle that with the current version of the JS ? If yes, any help will be appreciated

Thanks in advance!
