JQuery :: Selecting Elements That Ajax Has Not Delivered Yet

Here's some pseudo-code for reference:

$(document).ready(
function() {
... // #1 some code that fetches xml and generates a dom structure... <ol id='bla'><li></li></ol> then .appendTo('#foo');
... // #2 some code that generates another dom structure to be inserted into $('#bla').
}
)

The snippet #1 fetches xml and generates a dom to be appended to $('#foo'). But snippet #2 refuses to work with the id's created by the steps in #1. My guess is it is because #2 ran before #1 finished.

How do I make it so that #2 can reference the id's created by #1? Do I make #1 syncrhonous? Is there a way to make #2 run only after #1 is done? Do I just include onclick to the elements created by #1 -- I was hoping to avoid this because it appears the jQuery collective frowns on this.
