Angular js not updating dom when expected - angularjs

Question

I have a fiddle for this, but basically what it's doing it geo-encoding an address that is input into a textbox. After the address is entered and 'enter' is pressed, the dom does not immediately update, but waits for another change to the textbox. How do I get it to update the table right after a submit?
I'm very new to Angular, but I'm learning. I find it interesting, but I have to learn to think differently.
Here is the fiddle and my controller.js
http://jsfiddle.net/fPBAD/
var myApp = angular.module('geo-encode', []);
function FirstAppCtrl($scope, $http) {
$scope.locations = [];
$scope.text = '';
$scope.nextId = 0;
var geo = new google.maps.Geocoder();
$scope.add = function() {
if (this.text) {
geo.geocode(
{ address : this.text,
region: 'no'
}, function(results, status){
var address = results[0].formatted_address;
var latitude = results[0].geometry.location.hb;
var longitude = results[0].geometry.location.ib;
$scope.locations.push({"name":address, id: $scope.nextId++,"coords":{"lat":latitude,"long":longitude}});
});
this.text = '';
}
}
$scope.remove = function(index) {
$scope.locations = $scope.locations.filter(function(location){
return location.id != index;
})
}
}

Your problem is that the geocode function is asynchronous and therefore updates outside of the AngularJS digest cycle. You can fix this by wrapping your callback function in a call to $scope.$apply, which lets AngularJS know to run a digest because stuff has changed:
geo.geocode(
{ address : this.text,
region: 'no'
}, function(results, status) {
$scope.$apply( function () {
var address = results[0].formatted_address;
var latitude = results[0].geometry.location.hb;
var longitude = results[0].geometry.location.ib;
$scope.locations.push({
"name":address, id: $scope.nextId++,
"coords":{"lat":latitude,"long":longitude}
});
});
});
