set dynamic message from javascript validation rules like $(element).rules("add",

I need to set dynamic validation message for a custom date range validator for input from datepicker.

I have created a validator method like -

$.validator.addMethod("minMaxDatevalidation", function (value, element) { 
...})

And created a custom rule like -

$(element).rules("add", {
    minMaxDatevalidation: true,
    messages: { minMaxDatevalidation: "The " + fieldDisplayName + " field 
    must be on or after the " + moment(pastDate).format("DD/MM/YYYY") + "."
    }
});

But this validation messages in the above add rules section - this I want dynamic - for date selected than a particular year then above or if selected date is more than a particular year than future error message.

I tried to return custom message from validator addMethod, but it's not working.

Any help regarding setting dynamic message in the rules section would be great.

Using Jquery datepicker.
