[jQuery] using click() with $(event.target).is(something)

[light-blue]

I'm a Jquery newbie, so if this answer is available somewhere, please
let me know.

My user needs to click button B, which processes some info with AJAX
(working great), and then needs to programmatically click button A,
which itself runs an AJAX request. Button B works fine, but when it
tries $('a.buttonA').click() the code in button A doesn't run. I
suspect this is because I'm using $(event.target).is('a.buttonB'),
resulting in no binding for click() to run. Can anyone confirm? Any
suggestions to fix this?

Thanks!
