Another approach would be keep a fixed # of buttons. For example, if the list or table has 5 visible entries at a time, then just use 5 buttons, line them up with each entry in the list or table. When the list is scrolled up or down, you always know which entry is at the topmost entry, adjust your button actions accordingly. This way, you avoid maintaining an array of buttons and adjust the buttons positions due to list scroll.
