ajax link are quite fragile, they can have some problems because the js code is not embedded in the tag, but is attached to them using the id.
Checking the code of a page, you can see how all ajax lika are just tag a with an id like #yt1, and in the bottom of the page there is smth like:
That system sometime has problem, expecially when link are in some response.
If an ajax link have to me refreshed by an ajax request, I usually create ajax link like that:
Like that there are no id that can be ambiguous, it generate a tag with embedded his code. This kind of like always work, even after ajax request.
