Menu
I have an AngularJS app that I manually bootstrap at time 't'. At time 't + 1', I would like to show an HTML element that has no ng-controller attached. I would like to dynamically add a ng-controller to this element so it can communicate with my javascript code.
How can I do that?
PS I tried to dynamically add the ng-controller attribute to the element but it doesn't work.

To do that you need to compile elements.
HTML
<!DOCTYPE html>
<html ng-app="app">
<head>
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.1.5/angular.min.js"></script>
<link href="//cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/2.3.2/css/bootstrap.min.css" rel="stylesheet" type="text/css" />
<link href="main.css" rel="stylesheet" type="text/css" />
<script src="main.js"></script>
<meta charset=utf-8 />
<title>Angular JS</title>
</head>
<body ng-controller="parentCtrl">
<button ng-click="setCtrl2()">Set Controller</button>
<div id="placeholder">
<span></span>
<select>
<option></option>
</select>
<span class="input-append">
<input id="add" type="text" placeholder="Another one ?" ng-model="addName" />
<input type="submit" class="btn btn-primary" ng-click="addRow()" value="+ add" />
</span>
</div>
</body>
</html>
Javascript
angular.module('app', []);
angular.module('app').controller('ctrl', function($scope) {
$scope.rows = ['Paul','John','Lucie'];
$scope.name = 'Jack';
$scope.addRow = function(){
$scope.rows.push($scope.addName);
$scope.addName = "";
console.log($scope.rows);
};
})
.controller('parentCtrl', function($scope) {
$scope.setCtrl2 = setCtrl;
});
function setCtrl() {
var elem = document.getElementById('placeholder');
elem.setAttribute('ng-controller', 'ctrl');
var eSpan = elem.children[0];
var eSelect = elem.children[1].children[0];
eSpan.setAttribute('ng-bind', 'name');
eSelect.setAttribute('ng-repeat', 'row in rows');
eSelect.setAttribute('value', '{{ row }}');
eSelect.setAttribute('ng-bind', 'row');
var injector = angular.element(elem).injector();
var compile = injector.get('$compile');
var rootScope = injector.get('$rootScope');
var result = compile(elem)(rootScope);
// When outside of AngularJS you need to call digest
// rootScope.$digest();
}

You don't mention whether you've looked at previously asked questions. I found two which look like they could address the question you've asked:
Loading an AngularJS controller dynamically
How to bind an AngularJS controller to dynamically added HTML?
