view.html

<div class="control-group">
   <label class="control-label">Location</label>
   <div class="controls">
     <input name="location" type="text" placeholder="City, State, Country" value=""> 
     <input name="location_city" type="hidden" value="">
     <input name="location_state" type="hidden" value="">
     <input name="location_country" type="hidden" value="">
     <input name="location_lat" type="hidden">
     <input name="location_lng" type="hidden">
    </div>
</div>

view.js

      
function findComponent(result, type) {
  var component = _.find(result.address_components, function(component) {
    return _.include(component.types, type);
  });
  return component && component.short_name;
}

var autocomplete = new google.maps.places.Autocomplete(self.$('#coursera-profile-editor-location')[0], {types: ['geocode']});
  
google.maps.event.addListener(autocomplete, 'place_changed', function() {
    var place = autocomplete.getPlace();
    $('input[name="location_lat"]').val(place.geometry.location.lat());
    $('input[name="location_lng"]').val(place.geometry.location.lng());
    $('input[name="location_country"]').val(findComponent(place, 'country')); 
    $('input[name="location_state"]').val(findComponent(place, 'administrative_area_level_1')); 
    $('input[name="location_city"]').val(findComponent(place, 'administrative_area_level_3') || findComponent(place, 'locality')); 
});

You are missing the JS initial include.
