Cancelled date & time is still updated into Date Time input field

[shftdlt]

This looks like a bug, steps:

1. Open the cookbook sample: A vanilla Jet InputDateTime demo
2. The initial date/time selection is 01/01/13 12:00 AM
3. Click the ’Select Date Time’ icon to launch the Date Time picker
4. In the popup, click and select a different day, for example, 1/18/13
5. Click any place out of the popup to let the popup lose the focus
6. The date & time displayed in the input is not changed, say, it’s still 01/01/13 12:00 AM
7. Click the ’Select Date Time’ icon to launch the Date Time picker again
8. In the popup, the selected day and time is same as the one in step 4
9. Click the ‘Cancel’ button
10. Now the display in the input field is changed to 01/18/13 12:00 AM, while the text displayed in ‘Current component value’ is kept as previous '2013-01-01T00:00:00’
