You are binding event muilple time.

On click, you should just open modal. not bind. Bind should be done one time.

$('#reveal_AddSenderMod').on('click', function() {
  $('.modal.fade.modal-style2').modal('show');
})

$('.modal.fade.modal-style2').on('shown.bs.modal', function() {
    $(this).find('.modal-body').find('#loadURL').load('./loadPage.html').fadeIn('slow');
    return false;
  });

//Some dummy code

$('body').on('click', '#on-submit-senderid', function() {
        if(localStorage.getItem("review_submitte")) {
          return;
        }
        if(!$('input[name="sender_id_confirm"]').is(':checked')) {
            mkNoti(['Ops!'],['Please agree the condition to get Custom Sender ID'],{ sound: true, status:['danger'],dismissable: false });
            return;
        } else {
            $.ajax({
                            ...
                success: function(response) {
                    if (response.status == 'success') {
                        //SUCCESS
                        return false;
                    } else {
                        mkNoti([response.title],[response.message],{ sound: true, status:[response.status],dismissable: false });
                        return false;
                    }
                    localStorage.setItem("review_submitte", "true")
                }
            });
            hide_loader();
            return false;
        }
    });
