In a Web forms, from an ASP.NET code, I wish the button to change text and to execute some Javascript command. So far, I have this:

    Private Sub ShowText_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ShowText.Click
        ShowText.Text = "Michel"
    End Sub

This works. When I click on the button, the text of the button is changing. But, additionnaly to that, I wish to show a Javascript alert box for example. What else would be required at this point to achieve that?
