Add JavaScript functions

function ModalConfirm(msg, postbackurl) {
    $('#modal-msg').html(msg);
    $('#confirm-modal').modal({ backdrop: 'static', keyboard: false })
    .one('click', '#btnok', function () {
        if (postbackurl != '') {
            window.location = postbackurl;
        }
    });
}

function ModalAlert(msg) {
    $('#modal-msg-alert').html(msg);
    $('#alert-modal').modal({ backdrop: 'static', keyboard: false })
