Angular $scope variable not updating

Question

In my angular, I define a scope variable $scope.letter_content. When the view is loaded, I load string from my database and set it to $scope.letter_conten

Answer 1

Do not use plain values like this, you need to put such values into an object, so try in your controller:

$scope.obj = { letter_content: null};

and then in your view:

{{obj.letter_content}}
