Hi All
Im a newbie.
How can i edit item in todo app
Here my controller

.controller('TodoCtrl', function($ionicPopup, $scope, $timeout, $ionicModal, Projects, $ionicSideMenuDelegate, $ionicActionSheet) {

  // A utility function for creating a new project
  // with the given projectTitle
  var createProject = function(projectTitle) {
    var newProject = Projects.newProject(projectTitle);
    $scope.projects.push(newProject);
    Projects.save($scope.projects);
    $scope.selectProject(newProject, $scope.projects.length-1);
  }


  // Load or initialize projects
  $scope.projects = Projects.all();

  // Grab the last active, or the first project
  $scope.activeProject = $scope.projects[Projects.getLastActiveIndex()];

  // Called to create a new project
  $scope.newProject = function() {
    var projectTitle = prompt('Project name');
    if(projectTitle) {
      createProject(projectTitle);
    }
  };

  // Called to select the given project
  $scope.selectProject = function(project, index) {
    $scope.activeProject = project;
    Projects.setLastActiveIndex(index);
    $ionicSideMenuDelegate.toggleLeft(false);
  };

  // Create our modal
  $ionicModal.fromTemplateUrl('new-task.html', function(modal) {
    $scope.taskModal = modal;
  }, {
    scope: $scope
  });

  $scope.createTask = function(task) {
    if(!$scope.activeProject || !task) {
      return;
    }
    $scope.activeProject.tasks.push({
      title: task.title
    });
    $scope.taskModal.hide();

    // Inefficient, but save all the projects
    Projects.save($scope.projects);

    task.title = "";
  };

  $scope.newTask = function() {
    $scope.taskModal.show();
  };

  $scope.closeNewTask = function() {
    $scope.taskModal.hide();
  }
  
  $scope.selectTask = function(task) {
    // $scope.activeProject.tasks = task;
    // Projects.setLastActiveIndex(index);
    $ionicSideMenuDelegate.toggleLeft(false);
  };

  $scope.toggleProjects = function() {
    $ionicSideMenuDelegate.toggleLeft();
  };

  $scope.hold = function(task) {

   // Show the action sheet
    $ionicActionSheet.show({
      buttons: [
         { text: 'Edit' },
       ],
          buttonClicked : function(){
         }
      destructiveText: 'Delete',
      destructiveButtonClicked: function() {
        $scope.activeProject.tasks.splice($scope.activeProject.tasks.indexOf(task), 1);
        return true;
       
       }
    });
  };

   $timeout(function() {
    if($scope.projects.length == 0) {
      while(true) {
        var projectTitle = prompt('Your first project title:');
        if(projectTitle) {
          createProject(projectTitle);
          break;
        }
      }
    }
  }, 1000);

})
