i trying use not getting right

$timeout(function() {     angular.element('#areadata').triggerhandler('click');   }, 100);

if understood add space char textarea data when hit button:

app.controller('dummy', function($scope) {   $scope.spaceevent = function () {     $scope.mydata += " ";   }; });  <div ng-app="app" ng-controller="dummy">   <textarea id="areadata" ng-model="mydata"></textarea>   <button type="button" class="btn btn-danger" ng-click="spaceevent()">add space bar event</button> </div>
