i downloaded plugin , set in environment. on bootstrap v3.3.4 , jquery v2.1.3. able work in environment doing this:

html

<div class="row">     <div class="col-md-6">          <div id="card-4">              <div class="front">                  front content             </div>              <div class="back">                 content             </div>          </div>      </div>     <div class="col-md-6">         <button class="btn btn-success" id="flip-btn">click flip</button>      </div>  </div><!-- /.row -->  

jquery

<script>     $("#card-4").flip({       trigger: "manual"     });      $(document).on("click", "#flip-btn", function() {         $("#card-4").flip(true);         $(this).attr("id","unflip-btn").text("click unflip").removeclass("btn-success").addclass("btn-danger");     });      $(document).on("click", "#unflip-btn", function() {         $("#card-4").flip(false);         $(this).attr("id","flip-btn").text("click flip").removeclass("btn-danger").addclass("btn-success");     }); </script> 

hope helps. otherwise, put js , html jsfiddle can better diagnose problem.
