[Plugin: My Custom Widgets] Buttons

Anyone know how to get buttons to work in My Custom Widgets.
I created a custom widget with coding:

‘<p align=”center”>[button link=”http://wp.bearcreekchurch.com/media/”%5D Watch Service Live [/button]</p>
<p align=”center”>[button link=”http://bearcreek.podbean.com/”%5D Audio Podcasts [/button]</p>
<p align=”center”>[button link=”http://connections.bearcreekchurch.com”%5D Connections Magazine[/button]</p>’

The Button show up under the WordPress widgets “custom content”
But, if I create a My custom widget with the same code… I get only the HTML text above.. NO Buttons….

HELP!
