notifyDataSetChanged() weird behavior on Android 2.3.3

Question

I am implementing a chat window. It is working fine on 4.2 Emulator but weird acting on 2.3.3 Emulator. I have implemented a custom Adapter extending BaseAdapter to populate the ListVIew. ListView is refreshing the list respecting items base on who's message to display. Emulator 4.2 is refreshing the list as desired but on 2.3.3 list refreshes the with last selected item. Here is the code for my getView function.

public View getView(int position, View convertView, ViewGroup parent) {
    View chatItem = convertView;
    if (chatItem == null) {
        if (position % 2 == 0) //TODO: Change it to arrayListChat.getUpdater
            chatItem = ((LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.chat_item_me, parent, false);
        else
            chatItem = ((LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.chat_item_support, parent, false);

        ChatListItemViewHolder viewHolder = new ChatListItemViewHolder();
        viewHolder.textViewChat = (TextView) chatItem.findViewById(R.id.textViewChat);
        chatItem.setTag(viewHolder);
    }

    ChatListItemViewHolder viewHolder = (ChatListItemViewHolder) chatItem.getTag();
    viewHolder.textViewChat.setText(arrayListChat.get(position).getMessage());
    return chatItem;
}
