+###Tips
+
+####Live input typing validation
+If you want to validate the input, while user is typing (live), you have to refer to `ngModel`.
+As long as you use something like:
+```html
+<div ng-controller="MyCtrl as ctrl">
+<input datepicker type="text" ng-model="myDate"/>
+</div>
+```
+You can show validation errors simply validating the ngModel, as you would do for any other type of input, for example:
+```javascript
+.controller('Ctrl', ['$scope', function ($scope) {
+  var liveDate;
+  
+  $scope.$watch('myDate', function (value) {
+    try {
+     liveDate = new Date(value);
+    } catch(e) {}
+    
+    if (!liveDate) {
+    
+      $scope.error = "This is not a valid date";
+    } else {
+      $scope.error = false;
+    }
+  });
+}]);
+```
+
+Then your final html:
+```html
+<div ng-controller="MyCtrl as ctrl">
+<input type="text" ng-model="myDate" datepicker/>
+<div ng-if="ctrl.error">{{ctrl.error}}</div>
+</div>
+```
+
