Picker goes away on month/year change Windows Phone

OS: Windows Phone - Windows 8
Browser: IE11

Issue: When using the selectMonth/selectYear properties for pickadate, I'm having trouble getting the calendar to display after selecting a month/year. Once I select a month or year, the full screen "select" goes away, but the calendar never comes back (until you click/tap the input field again -- the month/year IS correctly selected though).

Expected: Select a month/year, calendar pops back up when select goes away.
Actual: Select a month/year, calendar is hidden.

Interim Fix: I updated my local version of pickadate to allow an option for a onMonthChange/onYearChange callback (which is fired from the change events in pickadate). Inside that callback, I just refocus the input so that the calendar displays again after using the select option.
