Delete All with no selection

[devappcloud]

the close button isn't working when no item selected.
I replaced the following code in ajaxcrud.js as quick solution
modal.addFooterButton("Close", 'btn btn-default', function (button, event) {
this.hide();
});
with
modal.setFooter('Close');

or we can edit addFooterButton function in ModalRemote.js to accept more option like (dismiss="modal").
Thanks you.
