Problem is in your anchor tag
Your reload problem is not due to your AJAX code, rather the anchor tags href. <a href="home.html" onclick="...."> when clicked will cause the current page to navigate to home.html.
Option 1: use href="#" instead of pointing to an external URL. Option 2: don't use an anchor tag at all. Replace the <a> tag with a <span> tag. Hope this helps.
