Popover - question: Use custom validator

[dougreese]

I am trying to create a popup with content that contains a button with an ng-click attribute, such as ng-click="save()". This is getting stripped out, with the message:

Removing disallowed attribute <BUTTON ng-click="save()">

I know how to create a custom Decorator that allows the use of specific attributes using a custom NodeValidator, but I don't know how to get that applied to contents of the popover-content div.
