In your managed bean you can try this code:

public void setPageDataTable() {
    final DataTable d = (DataTable) FacesContext.getCurrentInstance().getViewRoot()
        .findComponent("form:templateTable");
    int first = 1;
    if (d.getRowCount() % ROWS_DATATABLE == 0) {
        first = (d.getRowCount() - ROWS_DATATABLE);
    }
    else 
    {
        first = (d.getRowCount()/ROWS_DATATABLE)*ROWS_DATATABLE;
    }
    d.setFirst(first);
}

Call this method when you add a new row
