- * @name angular.directive.ng:watch
- *
- * @description
- * The `ng:watch` allows you watch a variable and then execute
- * an evaluation on variable change.
- *
- * @element ANY
- * @param {expression} expression {@link guide.expression Expression} to eval.
- *
- * @example
- * Notice that the counter is incremented
- * every time you change the text.

-        <input type="text" name="name" value="hello"><br/>
-        Change counter: {{counter}} Name: {{name}}
