       <ul class="small-10 small-centered columns">
          <li>
            <div class="error" if={this.email.error}>Required</div>
            <input onfocus="{focus}" onblur="{blur}" type="text" name="email" value="" placeholder="Email Address">
         </li>
      </ul>
    </form>

</script>

    this.focus = function() {
        this.session.focused = true;
        riot.update();
    };

    this.blur = function() {
       this.session.focused = false;
       riot.update();
    };

Use something like redux to store global app state.
