Jquery custom function not working

I have created a custom jQuery function that if assigned a target it will display a timer countdown but it isn't working am i missing something.  Here is the code.  Also there would be a div called timer as well.

          $.fn.extend({
                gtime:function(min){
                    var usrminutes = 60 * min,
                            display = $(this),
                            mins, seconds;
                    setInterval(function() {
                        mins = parseInt(usrminutes / 60)
                        seconds = parseInt(usrminutes % 60);
                        seconds = (seconds < 10) ? "0" + seconds : seconds;
                        return $(this).html(mins + ":" + seconds);
                        usrminutes--;

                        if (usrminutes < 0) {
                            usrminutes = 60 * min;
                        }
                    }, 1000);


                }
            });

$('#timer').gtime(1);
