title: Twitter Bootstrap Collapse Issue in IE-9
body: <p>I have a web application done in ASP.Net MVC4. I am using Twitter Bootstrap <a href="https://wrapbootstrap.com/theme/unicorn-admin-template-WB0F35928" rel="nofollow">UNICORN</a> theme in this application. I added Twitter Bootstrap <strong>collapse</strong> in one of the pages. But its not working in IE-9.The collapse is not opening on click in IE. I copied the HTML part of collapse given in <a href="http://twitter.github.io/bootstrap/javascript.html#collapse" rel="nofollow">Bootstrap-Collapse</a>
  to check if I have missed out any class/style but that is also not working. Is there any fix for this issue?</p>
