jQuery Validation conditional rule makes input never valid - valid always returns 0

I'm having a problem with jQuery validation conditional rules.

I specify a conditional rule for an element as such:

var validatorSettings = $("form").data('validator').settings; 
validatorSettings.rules = $.extend({}, validatorSettings.rules, {
        TimeFrameAmount: {
            number: function() { return $("select[name='TimeFrameUnits']").val() === "true"; },
            required: function() { return $("select[name='TimeFrameUnits']").val() === "true" } ;
        }
});

Problem is when I submit the form, $("form").valid() returns 0.

I traced is down to see that $("input[name='TimeFrameAmount']").valid() is the only element in the form that returns 0 and thus is the element causing the form to fail validation.

I further traced this down that $("input[name='TimeFrameAmount']").valid() always returns 0 and causes the form to fail validation even if the conditional rule functions both return false.

I checked this by setting a break point in the conditional rule functions, then triggered a call to $("input[name='TimeFrameAmount']").valid() from the Firefox console.

My conditional rules both return false and $("input[name='TimeFrameAmount']").valid() still returns 0 and the form fails validation.

One thing to note is that the errorPlacement callback in not fired when my conditional rules return false, which makes sense since no validation = no errors.

In fact, the input even has the "valid" class at the time I validate the form (and still has it after)

However, neither of those things prevent the valid() method from returning that 0

Any ideas how to get the form to pass validation?

Turns out the correct syntax to add conditional rules are:

TimeFrameAmount: { 
    required: { 
        depends : function () { 
            //check conditionality 
        } 
    } 
}
