Refresh Select2 without triggering change event

In Select2 v4 documentation recommended to reset select by setting value to empty value and triggering event.

$('#id').val('').trigger('change')

But how to reset dropdown select to placeholder without triggering change event and replacing tons of dom elements? Something like

$('#id').select2('refresh')

This appear to be an undocumented feature. I found the answer on stackoverflow, use 'change.select2'

$docInput.val(null).trigger('change.select2');

I might just document the change.select2 event as the recommended way to handle this.
