    obj.disabled = true;

    setTimeout(function() {
        var x = setInterval(function(){
                time= time - 1000; //reduce each second
                obj.value = (time/1000)%60;
                if(time==0){
                        clearInterval(x);
                        obj.value = "retry";
                        obj.disabled = false;
                }
        }, 1000);
