getCellLinkTemplate not working in AW 2.5.3 (maybe!)

We are upgrading AW to 2.5.3 from 2.0.1 to get it working on IE7 and WinXP. We had this code working fine in IE6, AW 2.0.1 version, but we dont see the link getting created in IE7.

var myGrid = new AW.UI.Grid;
       ::
        myGrid.setCellTemplate(function(col, row) {
            if (col == 6 ) {
                return this.getCellLinkTemplate(col, row);
            }
            else {
                return this.getCellNormalTemplate(col, row);
            }
        });

Is getCellLinkTemplate supported in latest version or is there a better way to do it?
