why is it empty?

(function ( $ ) {

    $.fn.ticket = function(options) {
        var opts = $.extend( {}, $.fn.ticket.defaults, options );
        console.log(opts);
        //console.log returns an empty object
        return this.each(function() {

        });
    };

    $.fn.ticket.defaults = {
        url: "api.mysystem.com/tickets",
        key: "89321kldska"
    };
};

}( jQuery ));
