How can I do to use tags hints in the Ask a Question section from my own advanced theme

Question

Greetings guys..!!

I want to use the same javascript functions from q2a core, such as: qa_title_change(this.value), qa_tag_hints(), etc.

I've tried naming input text equal to core  like "id=title: for "Ask a Question" and "id=tags" for "Tags". Addition, I put the called to scripts in my qa-theme.php.

<script src="' . $this->rooturl . 'js/qa-page.js"></script>
<script src="' . $this->rooturl . 'js/qa-ask.js"></script>

Maybe the answer is coding a plugin but I need some help to start.

Thank you so much..!!
