{on|once}('{type}') needs a function; ignored.

Raised by

The grid (core)

Since

1.0.1

What happened

on() or once() was called with something that is not a function, so nothing was subscribed. A no-op unsubscribe function is returned, so calling code is safe.

The fix

Pass the handler function itself, not its result - grid.on('sort:changed', handler) rather than handler().
