API scripts not triggering change:attribute the first time a attribute is changed but afterwards it works fine?

So i have like a normal input field with some attr name like <input name="attr_influence" class="characteristic-input" type="number" value="0"> And simple test API script like on('change:attribute', (ev) => {     const eventName = ev.get('name');     log(eventName); } So the first time i change the value in the input field i dont get an event triggered, but aftwards the event triggers fine. Is this a known issue or am i missing something?

It's possible the first "change" is actually creating the attribute, in which case it would get an "add:attribute" event.  Give this a try: on('add:attribute', (ev) => { const eventName = ev.get('name'); log(`Added Attribute: ${eventName}`); } on('change:attribute', (ev) => { const eventName = ev.get('name'); log(`Changed Attribute: ${eventName}`); }

Thanks as always
