Hi Anupam,

If We want to bind with text box in angular js then be use ng-bind directives.

Here, below we are using such bind in the program:

  <script>
  angular.module('binduserName', [])
  .controller('myController', ['$scope', function ($scope) {
   $scope.username =username;
   }]);
</script>
<div ng-controller="myController">
 <label>Enter User name: <input type="text" ng-model="username"></label><br>
  Hello <span ng-bind="username"> </span>!
</div>

Output:

Here ,when we changed with another text ,it will display that text in the below of textbox.
