 This is fix code for https://jira.appcelerator.org/browse/TIMOB-20357

 !!! You must use only $.addListener for fixed button NOT button.addEventListener  
 `win` argument can be omited if controller root is Window already.
 
 example:
    require('fix_timob20357').fix('myButton', $);
 */
exports.fix = function(buttonId, $, win) {
	if(!OS_ANDROID) return;
	if(!_.isFunction($.addListener)) {
		Ti.API.error("Can't apply fix tc5848 for this Alloy version");
		return;
	}
	
	var button = $.getView(buttonId);
	if(!button) {
		// button id can be changed, need exception
		throw "Can't find button: " + buttonId;
		//Ti.API.error("Can't find button:", buttonId);
		return;
	}
	
	if(button.apiName !== 'Ti.UI.Button' || !_.has(button._properties, 'backgroundImage')) {
		// not need fix;
		return;
	}
	
	win = win || $.getView();
	
	if(win.apiName !== 'Ti.UI.Window') {
		Ti.API.error("Can't apply fix without window");
		return;
	}
	
	// cleanup button
	var parent = button.getParent();
	$.removeView(buttonId);	
	var listeners = $.getListener(button);
	$.removeListener(button);
	parent.remove(button);
	var delayedProperties = _.pick(button._properties, 'backgroundColor', 'backgroundImage');
	
	// create clone of button
	button = Ti.UI.createButton(_.omit(button._properties, 'backgroundColor', 'backgroundImage'));
	
	$[buttonId] = button;
	$.__views[buttonId] = button;
	parent.add(button);
	
	_.each(listeners, function(evt) {
		$.addListener(button, evt.type, evt.handler);
	});
