Need to find date range using timeline slicer filter

Dear Kris,

I mapped as you said and that infact is a useful solution. I can get correct start date and end date from timeslicer if I use Hierarchy (custom visual). However, if I use Timeline Slicer (again a custom visual), I am getting static dates for Start Date and End Date. So there is a last piece of bug in the viz. My code is as follows:

newStartDate = CALCULATE ( MIN ( myNewTable[newDateColumn].[Date] ), ALLSELECTED ( myNewTable[newDateColumn].[Date] ) )

newEndDate = CALCULATE ( MAX ( myNewTable[newDateColumn].[Date] ), ALLSELECTED ( myNewTable[newDateColumn].[Date] ) )

Here is a snap shot of both the scenarios:

Case 1, the Start Date and End Date should've been 02-01-2016 and 06-01-2016, but it shows 01-01-2016 and 31-12-2017 instead.

Case 2, things are intact.

The problem is that I need to use the Timeline Slicer for my viz. Am confused why it works on one viz and not on another..!!
