        2. Treeitem and Treerow are only components that allowed to be item's children.
        3. A new treerow should be constructed and append to item, when treerow of item is null.
          Otherwise, when treerow of item is not null, modify the content of the treerow or detach the treerow's children first, since that only one treerow is allowed
        4. Do not append any treechildren to item in this method, a treechildren will be appended afterward.
        5. When a treerow is not appended to item, generally label of item is displayed.
        data - that is used to render the Treeitem
        index - the index of the data that is currently being rendered. Notice the index is the order of the siblings (i.e., data that belongs to the same parent).
