Ember Octane: ember-g-recaptcha reCaptchaResponse comes back as undefined

I am upgrading to Ember Octane and I am using ember-g-recaptcha https://www.npmjs.com/package/ember-g-recaptcha. The project README.MD has not been updated to reflect Ember Octane. The reCaptchaResponse in the component js keeps coming back undefined. How do I fix this?

I have posted the Ember-Twiddle here https://ember-twiddle.com/509eb1c04c9c7d908d16ba2a2bb39ba5. Note: you will need to provide a sitekey to use it.
