Assign on-click VBA function to a dynamically created button on Excel Userform

Question

I'm creating buttons dynamically on an Excel userform with the following code:

With Me.CurrentFrame.Controls.Add("Forms.CommandButton.1")
    .Caption = "XYZ"
    .name = "AButton"
    .Font.Bold = True
    .ForeColor = &HFF&
    ... blah blah blah
End With

I'd like to assign a function to run when these buttons are clicked, but I can't find a straightforward way to do this since there's no property as part of the button itself.

Is there a way to do this using the above idiom? Should I be going about this whole thing in a different way?

To add a control event dynamically in an Excel form; you need to first add the event(s) in a class module. For my example, I am going to add a class module named clsTEST with one event, btn_click()

    '#### CLASS NAMED clsTEST
    Public WithEvents btn As MSForms.CommandButton
    Public frm As UserForm

    Dim iCount As Long

    Private Sub btn_Click()

    iCount = IIf(iCount < 1, 1, iCount + 1)
    btn.Caption = "Count " & Str(iCount)

End Sub
'### END CLASS

As you can see, the only thing this will do is set the caption on the button to then number of times you clicked it. Next, in the form code enter the following:

    Dim mColButtons As New Collection    '## SET A NEW COLLECTION

    Private Sub UserForm_Activate()
    '
    Dim btnEvent As clsTEST
    Dim ctl As MSForms.Control
    '
    Set ctl = Me.Controls.Add("Forms.CommandButton.1")
    '
    With ctl
    .Caption = "XYZ"
    .Name = "AButton"
    END With
    '
    Set btnEvent = new clsTEST   
    Set btnEvent.btn = ctl
    set btnEvent.frm = Me
    '
    mColButtons.add btnEvent
    'End Sub

When you activate the form, it will create a button. every time you click on the button the caption will change.
