Dynamically change cell data or attributes

Hi All,

The following code seems right but stuffs up and makes odd cells bold:

obj.setCellText(function(col,row) {
if (this.getCellValue(13, row) == '9'){
obj.getCellTemplate(2, row).setStyle("font-weight", "bold");
return this.getCellValue(2, row);
} else {
obj.getCellTemplate(2, row).setStyle("font-weight", "normal");
return this.getCellValue(2, row);
}
}, 2);

Whats the best way to make a cells text bold depending on another cells value?
