Easiest way to fix this is to remove type="submit" from your button that calls the add() method, replacing it with type="button"
<input type="button" value="Save" ng-click='add()' class="btn btn-primary col-sm-offset-3" />
Otherwise, you need to add ng-submit="add()" on your form, and then remove the ng-click="add()" from your button with type=submit.
Your form should look like this:
<form class="form-horizontal" ng-controller="MyAddController" ng-submit="add()">
And your button like this:
<input type="submit" value="Save" class="btn btn-primary col-sm-offset-3" />
Either of these should work.
By the way, you don't need to use ; at the end of an ng-click instruction. Also, try using the button tag instead of input for the save button.
EDIT: You forgot to declare the app to use in your html. On the body of your HTML code, use ng-app='myApp'
