Steps to reproduce

please open the codepen link first then:

1. Open rangepicker then click recent two days , say you get a range [2017-11-20 15:01:28,2017-11-22 15:01:28], that's awesome.
2. Wait for 5 sec or 1 hour then click again, you still get a range [2017-11-20 15:01:28,2017-11-22 15:01:28], definitely wrong.

What is expected?

Range value should be [2017-11-20 15:01:33,2017-11-22 15:01:33].

What is actually happening?

Range value still be the same with the old value

---

By definition, the type of DatePickers ranges attribute is { range: string: moment[] }, this is wrong cause current time is not a constant, it should be { range: string: () => moment []}, then for every trigger you will always get the current time
