You only get events on the node where you called the subscribe command:

Node A                                                 Node B (A1)
()1> mnesia:start().                               ()1>  mnesia:start().
ok                                                    ok
()2> mnesia:change_config(extra_db_nodes, []).    
()3> mnesia:create_table(a,[{ram_copies,[]}]).
()4>                                               ()3>  mnesia:subscribe({table, a}).
()4>                                               {}
()4> mnesia:dirty_write({a,1,1}).                      
()5> 					      ()4> flush().
						      Shell got {mnesia_table_event,
