AfterUpdate Event Handling for a textbox class

I have a class that groups several textboxes in a userform for event handling. Here is the class:

Private WithEvents MyTextBox As MSForms.TextBox
Public EnableEvents As Boolean

Public Property Set Control(tb As MSForms.TextBox)
    Set MyTextBox = tb
End Property

Private Sub MyTextBox_Change()
    If EnableEvents = True Then
        'code for triggered event
    Else
        'No Trigger
    End If
End Sub

And here is the code inside the userform

Private Sub UserForm_Initialize()
    Dim ctrl As MSForms.Control
    Dim obj As clsTextBox

    Set tbCollection = New Collection
        For Each ctrl In Me.Controls
            If TypeOf ctrl Is MSForms.TextBox Then
                Set obj = New clsTextBox
                Set obj.Control = ctrl
                tbCollection.Add obj
            End If
        Next ctrl
    Set obj = Nothing
    EnableEvents = True
End Sub

I have a custom EnableEvents boolean so I can manually enable and disable the event firing when i need to (since Application.EnableEvents doesnt work in this situation).

The above code works great, except the change event happens every single time I type a character. In the past, I've used the AfterUpdate event on each individual textbox control, but it will not work on this class. Any ideas on how i can catch the event when the whole field is updated (afterupdate, exit, etc)?
