how can get render content in datatable event

GM_Lin

~~my datatable config
......
{
"targets": 11,
"render":function (data, type, row, meta) {
Stat= (data=="Y" ? "YES" : "NO");//data is 'Y' or 'N'

            return Stat;

}
.......

then i will in reload event get render text like this

var initDataTable=function() {
$("#datatable").dataTable().api().columns([6,7,8,9,10,11,12,13,14,15]).every(function (idx) {

    if(idx==11){
       //api only support column.data(),but i want to  get render text.......
       column.**text()**.unique().sort().each(function (d, j) {
           .......
       });
    }
});

}

table.ajax.reload(initDataTable);~~
