Events in tableview on Android

Goal: in relation to kind of event incrementing or decrementing of a value.

After click I increment a cell.

tv.addEventListener('click', function(e) {
    var total = 0;
    e.row.count++;
    e.row.countlabel.setText((e.row.count > 0)  ? '' + e.row.count : '');
    var prize = e.row.prizelabel.text;
    e.row.prize = e.row.count * parseFloat(prize);
    for (var i = 0; i < menue.length; i++) {
        total += rows[i].prize;
    }
    totalprize.text = total.toFixed(2) + ' EUR   ';
});

In tableview s list of products with prizes.

Now I want to decrement the count after other event.

• longpress only gives me the standard properties of source row, no index, no special custom properties
• swipe will mot fired.

Any ideas?
