iOS: setSelectedRow on picker not working if window not open

var win = Ti.UI.createWindow({

	layout: 'vertical'

});

var picker = Ti.UI.createPicker({

	type: Ti.UI.PICKER_TYPE_PLAIN,

	selectionIndicator: true

});

var data = [];

var answerLoop = 0;

// add answers

for (answerLoop = 0; answerLoop < 11; answerLoop++) {

	data.push(Ti.UI.createPickerRow({

		title: 'Answer ' + answerLoop,

		custom_item: answerLoop

	}));

}

picker.add(data);

// THIS IS WHERE THE BUG IS

// This should selected the value 'Answer 5' but as you can see, Answer 1 is selected at startup

picker.setSelectedRow(0, 5, true);

var selectedButton = Ti.UI.createButton({

	title: 'Select Answer 6',

	width: 300,

	height: 'auto'

});

selectedButton.addEventListener('click', function(e) {

	picker.setSelectedRow(0, 6, true);

});

win.add(picker);

win.add(selectedButton);

win.open();
