Get ID of dynamically added HTML elements?

Get ID of dynamically added HTML elements?

I am generating HTML based on user actions (in this case, populating a table with the result from AJAX calls).

In my context, I have a link where there is a Quantity field, which I would like to be editable. When I create the html, I give a unique ID to each row, (to reference to a JSON object), however I am unable to get the ID for said row, seeing as the DOM tree is parsed on the pageload and doesn't seem to update when I add elements to the page.

This means that $(this).parent('tr').attr('id') is not returning anything at all.

How would I make it so I can retrieve the ID of my row (which was created/added to the page after it was parsed)?
