Answer 1

There is no role of Angular in this. Its simple logic that you have to use. This Question is answered here for javascript.

UPDATE : This is another solution I found for your problem.

Answer 2

To get you started: Use ng-model to bind to model data and ng-change to react on any change in your input:

Total amount: <input type="text" ng-model="data.text" ng-change="countWords()" value="1230"></input>

in your controller:

$scope.data = {text:"", count:0};
$scope.countWords = function(){
  $scope.data.count = [count the words of $scope.data.text...]
};

then display the value in your view:

<textarea>{{data.count}}</textarea>
