.controller('MainController', function($scope, $http, $ionicModal, $timeout) {    var post = {};    $http.get("data/themeData.json")      .success(function(response) {        $scope.themeData = response.themeData;      });    $ionicModal.fromTemplateUrl('templates/post.html', {      scope: $scope    }).then(function(modal) {      $scope.modal = modal;    });    $scope.postShow = function() {      post = $scope.post = {};      $scope.modal.show();    };    $scope.cancelPost = function() {      $scope.modal.hide();    };    $scope.doPost = function() {      console.log('doPost-----');      console.log(post);      $timeout(function() {        $scope.cancelPost();      }, 1000);    };  })
