You don't need to run the code under document.ready(). it will work if u do like this.
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>Employee Profile</title>
<script type='text/javascript' src="http://code.angularjs.org/1.0.1/angular-1.0.1.min.js"></script>
<script type="text/javascript">
var myApp = angular.module("myApp", []);
myApp.controller("EmpCtrl", ['$scope', function ($scope) {
$scope.FirstName = "Angular";
$scope.LastName = "JS";
} ]);
</script>
</head>
<body>
<form id="form1" runat="server">
<div ng-app="myApp" ng-controller="EmpCtrl">
{{ FirstName }}
<br />
{{ LastName }}
</div>
</form>
</body>
</html></html>
