`Getmaildetailstable = $('#Getmaildetailstable').DataTable({
columnDefs: [{

}, {
data: "image",render: getStarredflag,
defaultContent: "",

}
order: [
[2, 'asc']
],
"searching": false,
"lengthChange": true
});

         function getStarredflag(data, type, full, meta) {
        var starflag=full.STARRED_FLAG; 
        if(starflag=="1")
        {
        return '<img src="wcp/theme/default/icon/action/star_icon1.png" />';
        }
        else if(starflag=="0")

It has been solved...
code modified like this..

if(starflag=="1"){
return '<img src="wcp/theme/default/icon/action/star_icon1.png" onclick="test()" />';
}
