I reported the same issue for v-if which got fixed in vue@2.0.0-rc.4. However, with this version the same code using v-show – which previously worked perfectly – does not work anymore.

Vue.js version

2.0.0-rc.4

Reproduction Link

http://codepen.io/analog-nico/pen/KgPKRq

Steps to reproduce

1. Click the link "Open popup using v-show"
2. A badly designed popup opens
3. Click the "Close" link

What is Expected?

• The popup closes successfully

What is actually happening?

• Vue fails to call an internal function and throws: TypeError: o.fn is not a function. (In 'o.fn(ev)', 'o.fn' is an instance of Object)
• The closePopupUsingVShow function attached to the "Close" link's click event never gets called.
• The popup does not close.

For reference the codepen contains the exact same implementation of the popup with the only difference that it uses v-if instead of v-show to show/hide the popup. v-if works perfectly.
