Describe the Bug
The AlertController inputs no longer accept min and max dates for a date input.

Steps to Reproduce
Steps to reproduce the behavior:

1. Create a blank project
2. Use the Angular example from the docs
3. See the TS Lint error Type 'string' is not assignable to type 'number'.

Related Code
None.

Expected Behavior
The min and max properties are supported for date inputs.

Additional Context
The commit 1d001a3 strong-typed min and max as number instead of string | number like it was before.
Issue is solved by using string | number again.
