Trigger onUpdate action in OctoberCMS

I have a form in OctoberCMS backend and I want to make a javascript trigger that will be fired when the user save the form so I can manipulate the form fields.

The official documentations of OctoberCMS Docs is not saying anything about it. Any suggestions are welcome.

Answer

Actually, it was in the Documentations of OctoberCMS:

Executes JavaScript code when the ajaxUpdate event is triggered on an element.

$('.calcresult').on('ajaxUpdate', function() {
    console.log('Updated!');
});
