Quick Answer
Handle dynamic content in widgets: use event delegation for child elements; on data updates, diff and patch the DOM rather than re-rendering entirely; expose an update method: $el.myWidget("update", newData). Use MutationObserver if the widget must react to external DOM changes. Avoid re-initializing the widget - update its internal state instead.
