1. Moved comment above a line to ensure that
maximum line length of 80 characters is not breached.
2. Removed a mistaken ()=> which was left behind (that would have
introduced the exact problem this change was intended to solve.)
This commit primarily fixes this issue:
https://github.com/koalyptus/TableFilter/issues/258
The fix here is to store a Sync call closed over "this" straight within
the object we're referencing. This having access to that object, we can
always retrieve the exact function reference/pointer/instance for removal
from handling events.
