As Ralf said, I was commenting specifically on your statement that
<input type=submit> was somehow "old style" or related to java or
certain frameworks.  That is indeed nonsense; <input type=submit> has
absolutely nothing to do with frameworks or particular programming
languages.

Yes, with <input type=submit> the label and the submit value are the
same, while they can be different things with <button type=submit>.
That has nothing to do with frameworks.  It certainly has nothing to
do with the OP's problem, which was that his submit button didn't have
a 'name' attribute, and thus wasn't being submitted with the form.
