I am passed 3 html elements as parameters to JS function. JS function is in separate file. I have problem to bind 'click' event with _confBtn object (which is parameter). My complete JS file:

 window.HAS = window.HAS || {};

HAS.MyApp = HAS.MyApp || {};



(function (_this, $, undefined) {

var _sessionTimeOut = false;

var _startCountDown = false;

var _counterTime;

var _countDownTime;

var _dialogWrap;

var _confBtn;

var _counter;



_this.init = function (showDialogTime, logofCountDownTime, dialogWrap, counter, confirmationButton) {



    _counterTime = 5;

    _countDownTime = 0;

    _dialogWrap = $('#' + dialogWrap);

    _confBtn = $('#' + confirmationButton);

    _counter = $('#' + counter);

    alert(_confBtn.text());

    createSessionTimeOut();

    $(document).bind(mousemove keypress mousedown mouseup, resetTimeOut);

}



_confBtn.on('click', function () {

    window.clearInterval(_startCountDown);

    _dialogWrap.css('visibility', 'hidden');

    createSessionTimeOut();

    $(document).bind(mousemove keypress mousedown mouseup, resetTimeOut);

});



function createSessionTimeOut() {

    _sessionTimeOut = window.setTimeout(function () {



        _dialogWrap.removeAttr(style);

        _counter.text(_counterTime);

        $(document).unbind(mousemove keypress mousedown mouseup);



        startCountDown();

    }, 2000);

}



function startCountDown() {

    _startCountDown = window.setInterval(function () {

        if (_counterTime >= 0) {

            _counter.text(_counterTime--);

        }

        _countDownTime++;

        if (_countDownTime >= 4) {

            logOutUser();

            return;

        }



    }, 1000);

}



function resetTimeOut() {

    window.clearTimeout(_sessionTimeOut);

    _sessionTimeOut = false;

    createSessionTimeOut();

}



function logOutUser() {

    $.ajax({

        url: '/MyApp/Account/LogOut',

        type: 'GET',

        success: function () {

            document.location.href = '/MyApp/Account/Login';

        }

    })

}



}(window.HAS.MyApp.SessionTimeOut = window.HAS.MyApp.SessionTimeOut || {}, jQuery));

I call in separate page like in following:

SessionTimeOut.init('5', '5', 'dialog-wrap', 'confirm-button', 'counter');

I have issue with _confBtn when I try to call click event. Browser show that is undefined.

Please help.
