[cocos-html5] cc.TableView not addChild increase ccs.UIPanel?

With Javascript/Web project this code will work:
@ tableCellAtIndex:function (table, idx) {
var cell = table.cellAtIndex(idx);
var *item = null;
if {
cell = new CustomTableViewCell;
*item = ccs.GUIReader.getInstance().widgetFromJsonFile(res.sjs_gui_ui_Scroll_tactics_list);
*item.setTag;
*item.setName("*formationitem"+idx);
cell.addChild;
cell.getChildrenCount;
} else {
*item = cell.getChildByTag(10);
}
return cell;
},
@
error:
cell.addChild (_item);—> without error, but you can not add
cell.getChildrenCount(); —> 0
