that a bug,
if I right remember there was an issue about it (maybe for j3)

@Fedik Yes rightly said; .addEventListner(), .triger() or change() are not currently working with jQuery. You can try by using .dispatchEvent() or .on() instead.

Glad to hear that its not my brain failure

@Megh05 no jquery is being used

@Fedik any ideas how to fix it?

Try like in this comment #17515 (comment)

but like this:
in calendar.js:

this.inputField.dispatchEvent(new CustomEvent('change', {bubbles: true, cancelable: true}));

then in your code you should be able to use:

yourField.addEventListener("change", ...

I not tested, in theory should work

Thanks I will take a look tonight

btw, the Issue from 2017,
well, that need to fix someday ?

I suggest we do it in 2023 ?

@Fedik it works!!!!

I am not going to submit a PR for this as I would probably put it in the wrong place etctetc and it will be quicker for you to add the oneliner than for us to go back and fro discussing changes that I dont understand

please test #32755

closing as we have a pr #32755
