HTML a href with id won't react on javascript click function

Question

With tutorials I am trying to create an export option from HTML table to excel with a custom file name.

Now I got a beautiful table already in HTML. I used many options, and I like to let this one work:

http://jsfiddle.net/RpKr8/

This is my tableToExcel.js:

var tableToExcel = (function() {
  var uri = 'data:application/vnd.ms-excel;base64,'
    , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
    , base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
    , format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
  return function(table, name) {
    if (!table.nodeType) table = document.getElementById(table)
    var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
    var blob = new Blob([format(template, ctx)]);
  var blobURL = window.URL.createObjectURL(blob);
    return blobURL;

  }

})()

$("#btnExport").click(function () {
    var todaysDate = moment().format('DD-MM-YYYY');
    var blobURL = tableToExcel('account_table', 'test_table');
    $(this).attr('download',todaysDate+'.xls')
    $(this).attr('href',blobURL);
});

This is the HTML table:

   <table class="table table-striped" id="account_table">
    <tr>
        <th>
            header 1
        </th>
        <th>
            header 2
        </th>
    </tr>
    <tr>
        <td>
            Testing Export
        </td>
        <td>
            Saved to todays date
        </td>
    </tr>
</table>
<div>
<a class="btn btn-success" id="btnExport">Export</a>
</div>

My problem is that when I press the Export button, nothing happens? I just dont get it, on every single fiddle it works. Iam working inside an iframe, although when Iam not this happens too.

How can I fix this? Or is there another way around?

<script type='text/javascript' src='//code.jquery.com/jquery-1.11.0.js'></script>
  <script type='text/javascript' src="//cdnjs.cloudflare.com/ajax/libs/moment.js/2.7.0/moment.min.js"></script>

Added these lines and it worked.

Also seperated the javscript code to:

<script type='text/javascript'>//<![CDATA[
$(function(){
var tableToExcel = (function() {
  var uri = 'data:application/vnd.ms-excel;base64,'
    , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
    , base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
    , format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
  return function(table, name) {
    if (!table.nodeType) table = document.getElementById(table)
    var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
    var blob = new Blob([format(template, ctx)]);
  var blobURL = window.URL.createObjectURL(blob);
    return blobURL;
  }
})()

$("#btnExport").click(function () {
    var todaysDate = moment().format('DD-MM-YYYY');
    var blobURL = tableToExcel('account_table', 'test_table');
    $(this).attr('download',todaysDate+'.xls')
    $(this).attr('href',blobURL);
});
});//]]> 

</script>
