I want to use listener in touchUi dialog like we do in Touch UI by adding listener node to respective node and write js for an event, I am not getting how to write listeners in touch ui . I saw an example from https://helpx.adobe.com/experience-manager/using/creating-touchui-events.html but this is globally making listeners active. I want to add listeners to some specific nodes. please assist how can i make it?
that document describes the way events are handled in Touch UI. If you need a lower level - then you can write your own custom types like how we wrote this custom Color picker.
Its all based on JQuery
Also - i recommend that you watch this Ask the AEM Community Experts session on Touch UI - they cover events there too:
