Ionic app having trouble on android 4.1

Hey so im doing an app in ionic and it works fine on my phone which runs 6.0 and everything works fine, so today i was gonna try it on android 4 or api 16 and the app is installed and opens however some of the functionality that works in 6.0 is now broken.

In my xml files i have the minsdk set to 14 so that shouldnt be the problem. My thought is that im perhaps using some ionic function that is not supported in 4.1 or something? The problem more specific is that it writes out the {{}} like that instead of fetching what it really is supposed to say a picture or a text etc.

Any help would be greatly appreciated.
