Callback actions raise error in select2 pattern #1470
Description
On Plone 6.1, I'm trying to use the select2 pattern with callback action for onSelected (but this also applies to onSelecting, onDeselecting, onDeselected).
If I pass the callback as a string referencing an existing JS function via pattern options (options["onSelected"] = "myFunction"), the JS throws an error at this line after a selection has been made in the select2 field :

Line 133 in 253d77a
Uncaught TypeError: this is undefined
The function is never called.
