Click handler for div added in column renderer ?

Hi,

I am adding a <div> and html table for a sparkline within a grid column renderer.

How can I add a on click listener to that div (string) within the renderer, since it won't yet be added to the DOM ?

Thanks !

simplified code...

Code:

columnSparklineRenderer: function(value, metaData, record, rowIndex, colIndex, store) {


        var    myData   = record.get('usefulStuff'),
                 sparkline = '<div id="' + "sparkline" + idValue + '" class="f-myGrid-sparkline"><table><tr>';


        for(var i=0; i<myData.length; i++) {


            var cellData = myData[i],
                cellClass  =  'myCellClass';


            sparkline += '<td style="width:5px" class="' + cellClass + '"></td>';
        }


        sparkline    += '</tr></table></div>';
        return sparkline + '<div style="font-weight:bold">' + value + '<div>';
    },
