csv button is not working properly

I am trying to implement the Export to CSV. I have included the following js files:

 
   <script src="js/jquery.min.js"></script>
    <script src="js/jquery.dataTables.js"></script>
    <script src="js/ColVis.js"></script>
    <script src="js/ColumnFilterWidgets.js"></script>
    <script src="js/media/js/jquery.dataTables.js"></script>
    <script src="js/extras/TableTools/media/js/ZeroClipboard.js"></script>
    <script src="js/extras/TableTools/media/js/TableTools.js"></script>
 

and I have used this following piece of code:

"sDom": 'CT<"clear">firtlip',
"oTableTools": {
    "sSwfPath": "swf/copy_csv_xls_pdf.swf",
    "aButtons": [ "csv" ]
}

The button is showing, but it is not exporting. Please assist me how to resolve this issue.

Thanks in advance.
