Stop form from processing

Dear all,

I am setting up my first Ninja form and I want to create a condition in order to process the form only when a certain amount of questions are answered correctly, so I created the following in javascript:

$J(‘#ninja_forms_form_9’).submit(function(e){
if(amount of question is correct){
}
else{
}
e.preventDefault();
return;
})

The good thins is that the data is not processed, but the submit button changes the submit text into processing and you cannot submit anymore.

Therefore am I wondering, how can I solve my bug? Either by adding code so that the submit button changes back to normal again, or by changing my code so that the submit button does not change.

I tried already return true/ false, or use break, but it all did not help.

Thanks a lot!
