BackgroundWorker 'DoWork' event not firing - vb.net

Question

I have a form that loads just fine, and I'm trying to fire off a task using a Background Worker as it loads.
I'm getting no errors with the code below, but the bw.DoWork event doesn't seem to be firing.
Am I missing something here? Thanks.
Here is my form Class -
Public Class mainForm
Dim objWorker As MyWorker
Private Sub mainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Call Me.loadForm()
End Sub
Private Sub btnCancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCancel.Click
Call Me.closeForm()
End Sub
Private Sub loadForm()
Me.objWorker = New MyWorker ' Invoke the background worker
End Sub
Private Sub closeForm()
Me.objWorker.bw_Cancel() ' Cancel the background worker
Me.Close() ' Close the form
End Sub
End Class
Here is my BackgroundWorker Class -
Imports System.ComponentModel
Partial Public Class MyWorker
Private bw As BackgroundWorker = New BackgroundWorker
Public Sub New()
bw.WorkerReportsProgress = False
bw.WorkerSupportsCancellation = True
AddHandler bw.DoWork, AddressOf bw_DoWork
AddHandler bw.RunWorkerCompleted, AddressOf bw_RunWorkerCompleted
End Sub
Private Sub bw_DoWork(ByVal sender As Object, ByVal e As DoWorkEventArgs)
Dim worker As BackgroundWorker = CType(sender, BackgroundWorker)
For i = 1 To 10
If bw.CancellationPending = True Then
e.Cancel = True
Exit For
Else
System.Threading.Thread.Sleep(500)
MsgBox("iteration " & i)
End If
Next
End Sub
Private Sub bw_RunWorkerCompleted(ByVal sender As Object, ByVal e As RunWorkerCompletedEventArgs)
MsgBox("Complete!")
End Sub
Public Sub bw_Cancel()
If bw.WorkerSupportsCancellation = True Then
bw.CancelAsync()
End If
End Sub
End Class

add to MyWorker constructor ('new' method) this line:
bw.RunWorkerAsync()
