Form_for reset button doesn't get updated to new form values after AJAX update


I’m trying to use the form_for reset button:
<%= button_tag ‘Reset’, :type => ‘reset’ %>

It works great, but when I update the object through AJAX, how can I get
the new form values to be the ones reset to? Right now it resets to the
values when the document loads, which makes sense. But is there a way to
get the reset button to register the new values?

Here’s the code:

Thank you for your time!

And hopefully something simpler than looping through all the fields and
manually setting their default values:
