So I'm assuming you have '$scope.disableClearMessage = true; ' in the controller.
Works for me.
Try 'disable-action="{{disableClearMessage}}"' and 'disable-action="disableClearMessage"' in the markup and inspect the button in the browser for each case.
The first should show 'true' (which is what you want) and the second show 'disableClearMessage' (which is obviously useless)
