onTouch does not get called for ListView child child

I am trying to do ListView reordering with drag and drop, and I'm using the DevBytes example as a base. onTouch() doesn't get called on my ListView when I touch the drag handle, that is, a child of one of the ListView's children.

As this didn't work, on my Adapter's getView(), I tried doing the following:

@Override
    public View getView(final int position, View view, final ViewGroup parent) {
        ViewHolder holder;
        LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        if (view != null) {
            holder = (ViewHolder) view.getTag();
        } else {
            view = inflater.inflate(R.layout.store_list_item, parent, false);
            holder = new ViewHolder(view);
            view.setTag(holder);
        }
        holder.storeName.setText(mShoppingLists.get(position).getName());
        holder.editButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                final FragmentManager manager = ((Activity) mContext).getFragmentManager();
                FragmentTransaction transaction = manager.beginTransaction();
                ShoppingListEditFragment shoppingListEditFragment =
                        ShoppingListEditFragment.newInstance(mShoppingLists.get(position).getId());
                transaction.replace(R.id.container, shoppingListEditFragment, "shoppinglistedit");
                transaction.addToBackStack(null);
                transaction.commit();
            }
        });

        holder.handle.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                ((DynamicListView) parent).onHandleLongClickListener(new DragEvent());
                return false;
            }
        });
        return view;
    }

This partially works, but as the touch listener only triggers for touches, and not for when the touch ends, this doesn't work properly. Why does this happen?

The touch listener is only giving you action_down events because you are returning false. If you return true you will also be sent corresponding action_move and action_up/action_cancel actions.

I can't remember which page of the documentation states this, otherwise I would link to it.
