    //this.more.find(".btn").on("click", function() { me.next_question() });
    //date controler
    var date = new Date();

    var day = date.getDate();
    var month = date.getMonth() + 1;
    var year = date.getFullYear();

    if (month < 10) month = "0" + month;
    if (day < 10) day = "0" + day;

    var today = day + "-" + month + "-" + year;       
    document.getElementById("theDate").value = today;

    //time controller

    function countdown(minutes) {
      
        var seconds = 60;
        var mins = minutes
        function tick() {
            var counter = document.getElementById("timer");
            var current_minutes = mins-1
            seconds--;
            counter.innerHTML =
    current_minutes.toString() + ":" + (seconds < 10 ? "0" : "") + String(seconds);
            if( seconds > 0 ) {
                setTimeout(tick, 1000);
            } else {
                 
                if(mins > 1){
            //alert("Time's up!")
            //return;
                 
               // countdown(mins-1);   never reach “00″ issue solved:Contributed by Victor Streithorst   
               setTimeout(function () { countdown(mins - 1); }, 1000);
                 
            }
        }
    }

countdown(5);


    this.question_input = frappe.ui.form.make_control({
        parent: this.page.main.find(".question"),
        df: {
            fieldtype: "Data",
            label: __("Que"),

start_answare: function() {
    var me = this;
    this.answare_input = frappe.ui.form.make_control({
        parent: this.page.main.find(".answare"),
        df: {
            fieldtype: "Small Text",

            label: __("Ans")
