If i have a TimePicker with a date-input template then the popup will not lose focus and disappear when you click elsewhere on the page (on another control input for example). When i bind to the popup 'show' property and attach handlers to the 'blur' and 'iconclicked' events i can get the popup to hide but on clicking 'Set' on the popup the 'change' event is never raised and the TimePicker input is not updated with the selected time.
