I have an AngularJS directive that has an input element in its template. Now I can add this directive inside a <form> tag and bind the ng-model without any issues.
The issue that I am running into is that the input that is being dynamically added into the <form> is not showing up in the formContoller which makes proper validation impossible.
Is there a way to have a directive that is being included with a <form> that has its own scope be able to dynamically add inputs that will be included in the formController that the directive is included in?
UPDATE
So as I was trying to build out the simpler example, I did figure out the root cause of the issue and that is the fact I am using $compile to generate the template used. I have created a simplified version of the issue occurring on plunker:

AngularJS Code
angular.module('directive', []).directive('containerDir', function() {
return {
scope: {
test: '@'
},
compile: function(element, attributes) {
return function(scope, element, attributes) {
scope.model = {
dataObject: {}
}
};
}
};
});
angular.module('directive').directive('inputDir', function($compile) {
return {
template: '<span></span>',
scope: {
model: '=dataModel'
},
compile: function(element, attributes) {
return {
pre: function(scope, element, attributes) {
var template = '<input type="text" name="username" ng-model="model.username" required />';
element.html($compile(template)(scope));
},
post: function(scope, element, attributes) {
}
};
}
};
});
template
<!doctype html>
<html ng-app='directive'>
<head>
<script data-require="jquery" data-semver="2.0.1" src="http://code.jquery.com/jquery-2.0.1.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<div container-dir>
<form name="testForm" nag-resettable-form style="padding-left: 20px;">
<div>
<label for="first-name">First Name</label>
<input id="first-name"
type="text"
name="firstName"
ng-model="model.dataObject.firstName"
required
/>
<div>value: {{model.dataObject.firstName}}</div>
<div>{{testForm.firstName.$error | json}}</div>
</div>
<div>
<label for="username">Username</label>
<span input-dir data-data-model="model.dataObject"></span>
<div>value: {{model.dataObject.username}}</div>
<div>{{testForm.username.$error | json}}</div>
</div>
<div>
{{testForm | json}}
</div>
<div style="padding-top: 1rem;">
<button class="primary" ng-click="model.submitForm()">Submit</button>
<button ng-click="resetForm(formReveal, {}, model.resetForm)">Reset</button>
</div>
</form>
</div>
</body>
</html>
Here is the same example without using $compile to show it does work without it:

Now I would still like to know if what I am trying to do it possible with adding input elements dynamically with directives that use $compile to generate the HTML for the directive.
While I might be able to rewrite the directive in question to not use $compile, I would still like to know if this is possible for future reference.
