[DatePicker] onChange is triggered too quick

Make sure these boxes are checked before submitting your issue - thank you!

• I have checked the superset logs for python stacktraces and included it here as text if any
• I have reproduced the issue with at least the latest released version of superset
• I have checked the issue tracker for the same issue and I haven't found one similar

Superset version

0.21dev

Actual results

When user changes input in Date picker, onChange event is triggered right away. In dashboard, this will cause new query send out for each slice.

Expected results

Can we trigger onChange only after user clicks "OK"?

Yes we should wait for Ok to call onchange

@mistercrunch, can you assign this to me? I have a working fix.

It appears it's not possible to assign to people who don't have write access.
