Http requests return same results!

I have an ionic 3 app which calls an external api. I called my api and it returned some results. I changed the api and changed the results. However, my ionic app, returned the same results over and over again. I had to uninstall my app and install it again to get it to work properly. What is causing this?

uninstall from what?

you have disable http request caching.

Uninstall from the device and install it again.

Will this work?

$http.get(api,{ headers: { 'Cache-Control' : 'no-cache' } })

Use Chrome’s developer tools’ Network tab to see what is going over the wire.
