I\'ve already looked over several posts on stack overflow asking virtually the exact same question yet none of what I found on those questions has helped. I\'m very new to
$(element).attr('title', 'NEW_TITLE').tooltip('fixTitle').tooltip('show');
Above code might help you.
$.tooltip(string) calls any function within the Tooltip class. And if you look at Tooltip.fixTitle, it fetches the data-original-title attribute and replaces the title value with it.
You can use the element id or class to make it more specific.
