onRowSelect update second lazy p:datatable with new data - jsf

Question

I hope someone will give me some hint about my problem. I have two <p:dataTable> that have lazy load. On first <p:dataTable> user can select row. According to selected row second <p:dataTable> must be updated with new lazy data (lazyModel2).
I don't know how to get new lazyModel2 and update second <p:dataTable> with new data on row select. onRowSelect event is working and I can get selectedRow data.
I just don't have any idea how to get new lazyModel2 from onRowSelect() method.
