AngularJS (Material) - Refresh data in md-list after adding new object using md-dialog
I'm new to the whole Angular world, but I ran into a problem yesterday that I can't fix. As a prototype, I am creating a simple Task application that allows the user to create, view, and delete tasks. A new task can be created by clicking a button that opens a dialog. Some information can be provided and by clicking "add task" the task will be added to the database.
The only problem is that after closing the md-list dialog that displays the list of items, it is not updated to show the newly added task. I tried using the "tack by" option for ng-repeat, but it didn't work.
I got information from this question: http://stackoverflow.com/questions/27874976/update-a-md-list-dynamically-from- angular
The code I am using to display tasks is one (simplified)
<html lang="en" ng-app="taskApp">
<head></head>
<body>
<div ng-controller="TaskController">
<md-list>
<md-list-item ng-repeat="task in tasks track by task.id">
<md-checkbox ng-model="task.checked" ng-change="updateTask(task)" aria-label="Complete Task"></md-checkbox>
<p>{{ task.title }}</p>
</md-list-item>
</md-list>
</div>
</body>
</html>
The template for the dialog looks like this:
<md-dialog aria-label="Create new task">
<md-content>
<md-card class="card-padding">
<form ng-submit="addTask(newTitle)">
<h2 class="md-title">Add a new task</h2>
<div layout="row">
<md-input-container flex>
<label>Title</label>
<input ng-model="newTitle">
</md-input-container>
</div>
<div layout="row">
<md-input-container flex>
<md-button class="md-raised md-primary" type="submit" ng-disabled="!newTitle || !newDescription">Add Task</md-button>
</md-input-container>
</div>
</form>
</md-card>
</md-content>
</md-dialog>
And the controller looks like this:
(function(angular) {
var TaskController = function($scope, $mdDialog, Task) {
Task.query(function(response) {
$scope.tasks = response ? response : [];
});
$scope.addTask = function(title) {
new Task({
title: title,
checked: false
}).$save(function(task) {
$scope.tasks.push(task);
});
$scope.newTitle = "";
$mdDialog.hide();
};
$scope.showDialog = function(ev) {
$mdDialog.show({
controller: TaskController,
templateUrl: 'taskdialog.tmpl.html',
parent: angular.element(document.body),
targetEvent: ev,
});
};
$scope.updateTask = function(task) {
task.$update();
};
$scope.deleteTask = function(task) {
task.$remove(function() {
$scope.tasks.splice($scope.tasks.indexOf(task), 1);
});
};
};
TaskController.$inject = ['$scope', '$mdDialog', 'Task'];
angular.module("taskApp.controllers").controller("TaskController", TaskController);
}(angular));
So I was wondering if anyone can help me with this problem.
Thanks in advance!

you are running a task in the task list in the wrong scope.
The following should get your job done. showing dialogue.
$mdDialog.show({
controller: TaskController,
templateUrl: 'taskdialog.tmpl.html',
parent: angular.element(document.body),
targetEvent: ev,
}).then(function(task){
$scope.tasks.push(task);
});
hiding the dialogue.
$mdDialog.hide(task);
