Currently, I am in the midst of my AngularJS learning journey where I am actively engaging with the material to improve my skills. However, there is one particular issue that has been puzzling me and eluding any clear solution.
Here's what I'm trying to accomplish:
Upon triggering an ng-click event, a function in my controller is invoked to $http-load HTML content (consisting of various divs and a form). Subsequently, I aim to "paste" this loaded content into my template within a specific div using ng-bind-html.
While the loading process functions as intended, I have encountered an obstacle. I am unable to assign values to the ng-models or {{someText}} within the loaded data. Instead, these elements inside the div (which serves as a modal-div containing dynamic content not present in the static template) return "undefined."
It's worth noting that I do not utilize Bootstrap or similar frameworks for this project.
How can I integrate this data into my scope effectively? Alternatively, are there alternative methods I could explore to achieve the desired outcome of having a modal div with dynamic content?
If it would aid your response, I can provide snippets of code. And please bear in mind, I am a complete newbie in this field! :-)

About My Directive:
workApp.directive('modalDialog', function() {
return {
restrict: 'E',
scope: {
show: '='
},
transclude: true,
link: function(scope, element, attrs) {
scope.dialogStyle = {};
if (attrs.boxWidth) scope.dialogStyle.width = attrs.boxWidth;
if (attrs.boxHeight) scope.dialogStyle.height = attrs.boxHeight;
scope.hideModal = function() {
scope.show = false;
};
},
templateUrl: 'app/tpl/modal.html'
};
});
Defined States:
.state('main', {
abstract: true,
templateUrl: tplMain
})
// PROJECTS
.state('main.projects', {
url: '/projects',
templateUrl: 'app/views/projects/project-list.html',
controller: 'projectListCtrl'
})
.state('main.projectdetails', {
url: '/projects/:projectId/details',
templateUrl: 'app/views/projects/project-details.html',
controller: 'projectDetailsCtrl'
})
Nested Views Within HTML Structure:
<!-- main -->
<div ui-view>
<!-- main.projects -->
<div ui-view>
<a ng-click="newProject()">New project</a>
</div>
</div>
<modal-dialog>{{message}}</modal-dialog>
Controller Implementation:
workApp.controller('projectListCtrl', function($scope, $rootScope, $http) {
$scope.newProject = function() {
$scope.message = '<div>Some HTML here...</div>'; // Loaded from $http.get
$scope.modalOpen = true;
}
});
In addressing my initial set of challenges, the inconsistency arises when attempting to display the modal upon invoking newProject(). This issue may be associated with the states/nested views structure – particularly since the modal-dialog exists in a separate view. Interestingly enough, replication of the modal-dialog component within the main.projects state leads to successful rendering.
A secondary concern involves the limited ability for {{message}} to support bindings, thereby hindering tasks like linking $scope.modal.title to {{modal.title}} within the HTML markup.
UPDATE:
An alternate approach – dynamically including an HTML file - has yielded positive results:
<div id="modal" ng-class="{ open: modal.data.visible }" ng-include="'app/views/' + modal.data.include"></div>
Accompanied by the following within the controller:
$scope.modal.data = {
include: 'projects/project-data.html',
visible: true,
title: 'New project',
subtitle: 'Enter project data',
projectName: 'My first project',
projectCompany: 'The Project Company'
}
While this method appears effective, I remain uncertain if favoring it over a directive – which remains troublesome to implement – aligns with best practices.
