asp.net mvc 4 - unobtrusive ajax form prevent cancel button from posting -

question: why cancel button posting controller submit?

i have form below loaded partial view. submit works fine. thing i've been struggling why cancel doesn't dismiss form. i've tried variety of things capturing click event. looked @ http://jimmylarkin.net/post/2012/05/16/broken-validation-on-cancel-buttons-with-unobtrusive-validation-ajax.aspx possible solution i'm not sure problem it's intended address. no doubt it's ignorance on part. bonehead thing missing?

//click event loading form.  <script>     $(document).ready(function () {         $('#editbtn').click(function () {             var url = "/quiz/editquiz?id=@id";             $.get(url, function (data) {                 $('#formdiv').html(data);                 $("#formdiv").show();             });         });   </script>  //form inside partial view.      @using (ajax.beginform("editquiz", "quiz", formmethod.post,                         new ajaxoptions                         {                             insertionmode = insertionmode.replace,                             httpmethod = "post",                             updatetargetid = "formdiv"                         })) {         @html.validationsummary(true)         @html.antiforgerytoken()         <div>             <fieldset>             .             .                           <input type="submit"  class = "btn btn-primary" value="save" />             <button  class = "cancel" >cancel </button>             </fieldset>         </div>   } 

i'm curious if cancel button whats causing submit default. try replacing <button class="cancel"> html helper. how @html.actionlink("cancel", "index"). link has text cancel , redirects action index.
