JavaScript event on addition of certain element

JavaScript event on addition of certain element

There is a page with list of URLs,
When User clicks on one of the URL, a JQuery Modal popup opens with list
of elements. Items in the list are added dynamically by doing AJAX call.
Each Item in the list has Raty & timeago (both JQuery Plugins){"5 star
rating, 2 Months Ago"}.
Now the problem is - Typically We execute JavaScript functions related to
these plugins at the time of page load in Document.ready event.
However, Now these functions need to be executed After items are added &
are ready for processing.
What is name of the event to handle?
