Review comment:
I think `this` context is wrong here. It's not the root element in
`setCommenECData`
Use anonymous function in `setCommonECData` is fine. JS engine will handle
it well and won't have a performance issue. Use a separate function with a
specified `this` context will be easy to have the above issue.
