Adding a button or a link to the Popup

Anonymous User

I am trying to add a button or a link to the popup that will do a custom action. As I have been directed to other questions, I did something like this

_createPopupMenuButton: function(){
        if(this.popupMenuButtonDesktop) {
          html.destroy(this.popupMenuButtonDesktop);
        }
        if(this.popupMenuButtonMobile) {
          html.destroy(this.popupMenuButtonMobile);
        }
          this.popupMenuButtonDesktop = html.create('span', {
              'class': 'popup-menu-button'
          }, query(".actionList", this.popupUnion.bigScreen.domNode)[0]);
