Category tag is generated asynchronously by ajax response. Therefore, I think that you cannot catch change event by general technique such as javascript and change() methods of jQuery. So that dkd903 says, it may be necessary to change qa-ask.js directly. Because I do not know javascript very much, I want to wait for the answer of other engineers.

There is already a javascript function qa_category_select(idprefix, startpath) change it from /qa-content/qa-ask.js file.
