Describe the Bug
When using ion-datetime, for each column if I choose the first value then it does not show anything.

Steps to Reproduce
Steps to reproduce the behavior:

1. Use ion-datetime
2. Fill in 01 Jan 2018 (first option for every column)
3. Result empty (the value is from placeholder)
4. Fill in 02 Jan 2018
5. Only the Date is there, Month and Year are still empty

I can also reproduce this issue with @ionic/angular@4.0.0-alpha.7 and the new docs (locally).

Thanks,
