I’m not able to add data to a dynamically added element:

var newItem = "<li>" + poi.Title + "</li>";
$(newItem).data('poiID', poi.ID);
$(newItem).data('poiTitle', poi.Title);

I’ve tried to add this:

alert($(newItem).data('poiID'));

right after the above line, but I keep getting “undefined”.

    Change your code like so:

    var newItem = $("<li>" + poi.Title + "</li>");
newItem.data('poiID', poi.ID);
newItem.data('poiTitle', poi.Title);

...

alert(newItem.data('poiID'));
