jquery plugin - define a variable options that contain other variables or functions

I'd like to know if is possibile in a jquery plugin define a variable options that contain other variables or functions

$.fn.Plugin.defaults = {
    pagelabels: "Page " + current + " of " + totalPages;
    total: "The total is " + getTotal.call(this);
};

$.fn.Plugin = function(options) {
    var options = $.extend(true, {}, $.fn.Plugin.defaults, options);

    return this.each(function() {

        var current = 10;
        var totalPages = 100;

        $('#page').text(options.pagelabels);
        $('#total').text(options.total);
    });
};

function getTotal() {
    return 2000;
}

Is there a way to do this? Thank you
