In order for your code to work, you will need a Google API key. You will need to open up the PlacesController, search for onSearchfieldKeyup, and replace 'enter key here' with your key.
You also need to go into your Google API Console, go to Services, and switch on the Places API.
Please note that because we dynamically create a URL for our store, clicking Load Data on the store in the Project Inspector will not work.
