Getting option-buttons to be more responsive

When you use the (supercool) option-buttons that appear when you swipe a list item (example here: it is really fast and responsive. But only when you have one item in there as per the example.

When I try to put more than one item in there. Say {{book.title}} by {{}} it gets janky and non-responsive. It is worse if I put actual markup in there.

It seems to work if I stick an image in there but otherwise is a little screwy. Anyone having similar problems? Any pointers?

Hmm, just to clarify when you say more than one item, do you mean something like this:

Sounds like it could be a bug, what device and which version of Ionic are you using?
