Add and remove data-required

[sctechcgms]

I have the following JS order:

$ ( "# Aux"). Change (function () {
             $ ( "# Name") focus ().;
             $ ( "# Name") closest ("div") removeClass ("error")..;
             if ($ ( "# aux"). val () === "Physics") {
                 $ ( "# Organ") attr ("data-required", true).;
             } Else {
                 orgao.removeAttr ("data-required");
             }
         });

But even with the removeAttr () function when I try to send the form, the validate () again adds class 'error'

Same problem here: after deleting all data-* attributes and 'error' class from inputs, after trying to submit the form, plugin adds again 'error' class to input, thus blocking the form submit.
