AngularJS Save Browse History

I'm trying to solve a problem. I want that when a perform an action or function in the controller to be saved in the brose history. For example, I want to do this:

• Type something in a textbox.
• Click a link to call a function that will set the string I typed to a variable in $scope and save it at the browser history.
• Do the same as the previous step with a different value.
• If I click the "back" button from the browser, I want to display the first value I entered.

I have a very simple example of what I want but I don't know what do I have to add to be able to use the "back" and "forward" button from the browser.
