title: meteor app: how to properly use a button to influence the route
body: <p>I'm working on a survey/wizard type of meteor application.
  The interface will only have two navigation buttons, who's caption/value will be determined dynamically based on whatever step a given user is currently at.
  My question is: what markup syntax should I use within each of these two button's definitions in order to direct the Iron Router to change the route. Another words, where in the button definition should I put this: this.redirect('/anotherpath') ?</p>
