Check and Next button into a single button - h5p and Moodle

Hi H5P Community,

I'm trying to make the "Check" button and "Next" button into a single button on a Moodle project.

See screenshot:

So if a user selects an answer from the Multiple Choice section, and the user clicks on "Check", 

if the answer is correct the button text should change to "Next". Then if the user clicks the Next button, he/she will navigate to the next question.

Is something like this possible? 

If so how can this be achieved?

Is it possible to check results from inside the h5p iframe from outside the iframe?

Thanks in advance!

Gr,

Amisi
