pass rownumber to remoteCommand using Primefaces

Question

Context: xhtml, java, jBoss.

It's working, ok:

-inside dataTable tags-

<p:ajax event="rowEditInit" onComplete="nestedTableRefresh();" ... />

-beyond dataTable tags-

<p:remoteCommand name="nestedTableRefresh" update="form:view:person:1:address" ... />

Question:

How to pass row number to the update parameter content as rownum value / index of edited row (where rowIndexVar="rownum" in the dataTable)?
