on master record edit page, reload a detail record when js event on other detail record is clicked

Hi,
I have a master record edit page with two linked details tables, I use one of them as a list of options that when i click on a grid of it, it will create a record in the second detial table, its working fine to this step.
But is there a way to also reload the second detial table that had a new record incerted on? to be able to see the added record instantly,
I tried this code on the client after of grid click event (in the first deital table):
var detailsPage = pageObj.getDetailsPage( 'second_detials_table' );
detailsPage.reload( {} );
But it only work if the js event was in the master record , not another detial table connected to the same master record.
Any trick to auto reload the second detial table using the same event?
