Question

Im having an issue regarding my suggest textbox, when i add a new row, all the fields are fine except the suggest tag textbox. Code snippet is as below... 

var table = document.getElementById(tableID);


            var rowCount = table.rows.length;
            var row = table.insertRow(rowCount);
            var colCount = table.rows[1].cells.length;

            for (var i = 0; i < colCount; i++) {
                var newcell = row.insertCell(i);

                newcell.innerHTML = table.rows[1].cells[i].innerHTML;

                switch (newcell.childNodes[0].type) {
                    case "text":
                        newcell.childNodes[0].value = "";

                        break;
                    case "checkbox":
                        newcell.childNodes[0].checked = false;
                        break;
                    case "select-one":
                        newcell.childNodes[0].selectedIndex = 0;
                        break;
                }
