Disabling cache in wpe-webkit-mir-kiosk

I have a angular app running in wpe-webkit-mir-kiosk with the help of Nginx server.

The UI has Button with call a API GET method to get data, but after i refresh the Angular app the GET method gets called automatically without touching the UI button, what can be the issue?

If it is caching how can i disable caching in wpe-webkit-mir-kiosk

Thanks in advance
