Global notification to change element in all views


Hi Guys,

If i would like to show a “bell” icon to the right side of each views header when the user receives a push notification on IOS, There are all separate HTML views for each page.
How would i achieve something like this?

I think i need to look at global broadcasts?

Current setup: A alert message is shown, but i would like it more graphical instead of prompting the user.
