How can I detect when jQuery Validation is done, and call something based on that event?

I'm new to jQuery.

Working with jQuery validation plugin & cufon at the same time is giving me really hard time.

Basically, I want to detect event once jQuery Validation did what it had to do and call Cufon.refresh() straight after it.

$('#commentForm').validate({
    rules: {
        password: {
            required: true,
            minlength: 8,
            maxlength: 8,
            number: true
        },
    }
});

We are expecting <label class="error"> SOME TEXT </label> when form is not valid.

And once that created I want to Cufon.refresh() on that label created by jQuery Validation. How can I detect when jQuery Validation is done, and call something based on that event?

Any help much appreciated. Regards, Piotr

Thanks to @Ariel - if there is a 'success' there has to be a 'not-success' as well, so..

Working code:

$('#commentForm').validate({
    rules: {
        password: {
            required: true,
            minlength: 8,
            maxlength: 8,
            number: true
        }
    },
    showErrors: function(errorMap, errorList) {
        this.defaultShowErrors();
        Cufon.refresh();
        //alert('not valid!')
    },
    success: function() {
        //alert('valid!')
    }
});

Thanks again for the idea!
