TableTools download button plug-ins not working

Ramprakash

Hai all, I am using datatable for my sample application. I need to use TableTools extension for my application but my app won't support flash buttons so sSwfPath is useless for me. I found download button is the alternate option. When I tried to design my app following the examples the download button is not getting to my application rather warning is displyed.. It dispalys error alert as "TableTools: Warning - unknown button type: download"

Here are my code. Please tell where am I wrong..

/**

var table;
var colIndex;
var sortingOrder;
var currentPage;

TableTools.BUTTONS.download = {
