with this, you can clear all filters, when binded on button

$.fn.dataTableExt.oApi.fnResetAllFilters = function (oSettings, bDraw/default true/) {
for(iCol = 0; iCol < oSettings.aoPreSearchCols.length; iCol++) {
oSettings.aoPreSearchCols[ iCol ].sSearch = '';
}
$('.filter-term').remove();
oSettings.oPreviousSearch.sSearch = '';
if(typeof bDraw === 'undefined') bDraw = true;
if(bDraw) this.fnDraw();
}
