How to use $(document).trigger('updateTableUrl', ....) for specific table in a page

[ReyDev]

I want to use $(document).trigger('updateTableUrl', ....) in a page that has 2 tables on it. so when the command triggers, 2 requests send to the server, the server returns 2 JSONs. but I want to use this trigger for one of them. how can I do it? (how should I specify the table )
