Issue Description

I am attempting to set the badge value of a tab, while that tab is not the one currently visible. For example, I want tab 3 to update its badge value, while tab 5 is the currently selected one. I know my functions and notification methods are working fine, because I am able to console log a test string to ensure that it is being hit. It appears that the only time a badge can be updated, is when the tab the badge belongs to, is the currently selected tab.
