Callback to previous view

i am quite new to ionic and AngularJS. Started coding my first application a few weeks ago. Currently i am running into a problem:

I need to pick a value from a list and send the value back to the previous view. So lets say i wanna select which car i’m driving, i click a button, a new page opens with a ion-list with options. When i pick one, i wanna make a callback to the previous view and update those values (and also go back to the previous screen so i can watch the changed value).

How can i do this? Thanks!
