Outlook 2013 - VBA - Ribbon - onLoad not working

In %appdata%\Microsoft\Office\olkapptitem.officeUI

I have:

<?xml version="1.0" encoding="UTF-8"?>
<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui" onLoad="DoIt">
    <ribbon startFromScratch="false">
        <tabs>
            <tab idMso="TabMail">
                <group id="group1" label="Hazaa!">
                    <button id="one" onAction="DoIt2" label="hi" visible="true"/>
                </group>
            </tab>
        </tabs>
    </ribbon>
</customUI>

      

        
        
        
      

    

In Outlook, in a VBA editor, I have a module called Module1 that has:

Option Explicit

Sub DoIt(ribbon As IRibbonUI)
    MsgBox "hi"
End Sub

Sub DoIt2(control As IRibbonControl)
    MsgBox "bye"
End Sub

      

        
        
        
      

    

However, neither will be executed DoIt

, either DoIt2

. If I select options from DoIt2

, then when I click the button it starts, but not vice versa.

Any help is appreciated.
