Quick Answer
Handle dynamic content with event delegation: $("static-parent").on("click", ".dynamic-child", fn). For dynamically loaded content via AJAX: use callbacks after $.ajax success to initialize plugins on new elements. Use MutationObserver for framework-generated content that jQuery doesn't control. Avoid re-running initialization on the whole page - only target new elements.
