How to get hidden rows ?

I have used hidden to remove column from datatable list on delete button. but when I use $$(datatable).serialize() then I don’t get hidden rows. how can I get hidden rows in list ?

var item = this.getItem(id.row);
item.hidden = item.hidden ? false : true;
this.filter(function (obj) {
return !obj.hidden;
});

try to use table.serialize(/*all*/ true)
