[jQuery] Validate, Remote and Custom Rules -- disable and enable a submit button.

[jQuery] Validate, Remote and Custom Rules -- disable and enable a submit button.

I tried to make a remote validation with custom rules (return true or false) on a input field.
I do wanted to disable the submit button, I already did.
$("#submit").attr("disabled", "disabled");
However, I am clueless how could I enable it back again? Upon return of true?
Here's my js code:

Is there a way to re-enable the submit button easily?
