AngularJS: Error: No controller: form - angularjs

Question

HTML:
<div ng-app="my-app" ng-controller="AppController">
<ng-form name="myform">
<gtux-el></gtux-el>
</ng-form>
</div>
JS
var app = angular.module('my-app', [], function () {
})
app.controller('AppController', function ($scope) {
})
app.directive('gtInputMsg', ['$compile', '$interpolate', '$log', function($compile, $interpolate, $log) {
function link($scope, element, attrs, ctrls) {
var modelCtrl = ctrls[0], formCtrl = ctrls[1], msgCtrl = ctrls[2];
element.on('click', function() {
console.log('gt-input-msg:click', element)
});
};
return {
require : ['ngModel', '^form', 'gtInputMsg'],
link : link
};
}]);
app.directive('gtuxTextfield', ['$compile', '$timeout', '$log', function($compile, $timeout, $log) {
return {
restrict : 'E',
template : '<input type="text" name="field" gt-input-msg ng-model="fieldvalue" />',
replace : true
};
}]);
app.directive('gtuxEl', ['$compile', '$timeout', '$log', function($compile, $timeout, $log) {
function link($scope, $element, attrs, ctrl) {
//here compile is used because in my use case different elements are used based on some option values. A service provides the template to be used based on a key
var $cr = $compile('<gtux-textfield></gtux-textfield>')($scope);
$($cr).appendTo($element);
}
return {
restrict : 'E',
link : link,
transclude : true
};
}]);

Demo: Fiddle
As far I can see there is a ng-form element at the top of the hierarchy which should provide the from controller to the gtInputMsg directive.
How can this be rectified?

You're compiling the <gtux-textfield> element without it being under the form in the DOM as you haven't appended it yet. Try:
var $cr = $('<gtux-textfield></gtux-textfield>').appendTo($element);
$compile($cr)($scope);
In your gtuxEl link function.
