If you want to select all values in the multiselect (when "All" selected), you can use:

select: function(e) {
    var dataItem = this.dataSource.view()[e.item.index()];

    var values = dataItem.value === "ALL" ? 
        $.map(this.dataSource.data(), function(dataItem) {
            return dataItem.value;
        }) 
        : this.value();

    this.value(values); // values holds all items within the multiselect

}
