Oooh, that's an interesting idea... 

Added these few lines to the index.hbs file. I think the only way is to
bind the function to a window.* variable isn't there?

     {{#if consentText}}
         <script type='text/javascript' > window.getConsentText = function () { return `{{ consentText }}`; } </script>
     {{else}}
         <script type='text/javascript'> window.getConsentText = function () { return ""; } </script>
     {{/if}}


Another question is if we'd like to have customizable buttons. On
one hand 'I agree' and 'I decline' probably cover 99% of the use-cases,
(especially as we can translate it) but we could still add something like
"<agree-text>|<decline-text>" to the end of the consent.txt file. For
example:

     YES|NO

or 

     Agree|Decline

or (this won't show the disagree button)

     Agree|
