Events listeners are not unbound when reusing nodes

[posva]

Vue.js version

2

Reproduction Link

http://jsfiddle.net/posva/hdqz1bc3/

Steps to reproduce

1. Click the toggle
2. select a value in the select

What is Expected?

No error in console

What is actually happening?

The select is trying to fire the change from the previous select. Adding a key attribute to one of the selects is a workaround @rorc

Seems an edge case for update-listener

old.length = cur.length
for (let i = 0; i < old.length; i++) old[i] = cur[i]

cur is a function type here, so it breaks. I'll fix it.

@posva I have forked your JSFiddle example ,and I found that if your added @change="foo" to the select2,it can run normally. http://jsfiddle.net/jimczj/hm0onwy9/1/

@jimczj Yes, that makes the function defined when trying to invoke it
