Excel Worksheet_Change not detecting changes - excel

Question

Unfortunately Worksheet_change is not working for me. I am using a Sheet where the first column is NOW() function. If I click anywhere in the excel the time on this cell changes, but the Worksheet_Change just don't detect it.
A2 is using =NOW()
Anyone knows how to fix this issue? I have tried several different ways and no one works.
'Option Explicit
'Option Base 1
Dim xVal As Double
'Update by Extendoffice 2018/8/22
'Private Sub Worksheet_Calculate(ByVal Target As Range)
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
If Target.Address = Range("$A$2").Address Then
'Rows(3).Insert Shift:=xlDown
'Range("$A$3").Value = Now
'Range("$B$3").Value = xVal
'Range("$C$3").Value = Range("$C$2").Value
'Else
If xVal <> Range("$B$2").Value Then
Debug.Print xVal & " <- xVal IF"
Debug.Print Range("B2").Text & "<- Text IF"
Rows(3).Insert Shift:=xlDown
Range("$A$3").Value = Now
Range("$B$3").Value = xVal
Range("$C$3").Value = Range("$C$2").Value
End If
End If
Application.EnableEvents = True
End Sub
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
xVal = Range("$B$2").Value
End Sub

Cell A2 in worksheet Sheet1 contains the formula =B2.
Sheet1
Option Explicit
Private Sub Worksheet_Calculate()
WsCalc
End Sub
' Only to trigger the calculate event when different cell is selected.
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
ThisWorkbook.Worksheets("Sheet1").Range("B2") = Int(Rnd() * 2 + 1)
End Sub
ThisWorkbook
Option Explicit
Private Sub Workbook_Open()
WsCalc
End Sub
Module1
Option Explicit
Public lngSource As Long ' Current Source Value
Sub WsCalc()
Dim rngSource As Range ' Source Cell Range
' Create a reference to Source Cell Range (rngSource).
Set rngSource = ThisWorkbook.Worksheets("Sheet1").Range("A2")
' When the workbook opens, Current Source Valuec (lngSource) is equal to "".
' Therefore:
If lngSource = 0 Then
' Initialize Current Source Value (lngSource) i.e. write value
' of Source Cell Range (rngSource) to Current Source Value (lngSource).
lngSource = rngSource.Value
MsgBox "Monitoring started (lngSource=" & lngSource & ")."
Exit Sub
End If
' If you need disabling events, this is how you implement it. Not needed
' in this code.
' Application.EnableEvents = False
On Error GoTo ProgramError
' Check value of Source Cell Range (rngSource)
' against Current Source Value (lngSource).
If rngSource.Value <> lngSource Then
' The value has changed.
MsgBox "The value has changed from '" & lngSource & "' to '" _
& rngSource.Value & "'."
lngSource = rngSource.Value
Else
' The value hasn't changed (usually no code).
MsgBox "Value NOT changed, still '" & lngSource & "'"
End If
SafeExit:
' MsgBox "Enabling events before exiting."

Exit Sub
ProgramError:
' Improve this error handling.
MsgBox "An unexpected error occurred."
On Error GoTo 0
GoTo SafeExit
