Tips for managing a basic click event within the Backbone.js framework

I am facing a challenge with a basic functionality in Backbone. I am trying to set up the <h1> element on my page so that when a user clicks on it, it smoothly navigates back to the homepage without a page reload.

Here is the HTML snippet:

<h1><a id="home" href="/">Home</a></h1>

(UPDATE: corrected the ID as per the suggestion from a commenter.) Below is my Backbone view and router code:

var HomeView = Backbone.View.extend({
  initialize: function() { 
    console.log('initializing HomeView');
  },
  events: { 
    "click a#home": "goHome"
  }, 
  goHome: function(e) { 
    console.log('goHome');
    e.preventDefault();
    SearchApp.navigate("/");
  }
});
var SearchApp = new (Backbone.Router.extend({
  routes: { 
    "": "index", 
  },
  initialize: function(){
    console.log('initialize app');
    this.HomeView = new HomeView();
  },
  index: function(){
    // perform actions here
  },
  start: function(){
    Backbone.history.start({pushState: true});
  }
}));
$(document).ready(function() { 
  SearchApp.start();
});

The console output displays

initialize  app
initializing HomeView 

However, when clicking on the <h1>, the page reloads - and goHome is not logged in the console.

What could be the issue here? While I can easily achieve the click event binding for <h1> using jQuery, I am keen to grasp the correct approach in Backbone.

To utilize pushState, all clicks must be intercepted to prevent page refresh:

$('a').click(function (e) {
  e.preventDefault();
  app.router.navigate(e.target.pathname, true);
});

An example implementation could look like this:

$(document).ready(function(){

  var HomeView = Backbone.View.extend({
    initialize: function() { 
      console.log('Initializing HomeView');
    }
  });

  var AboutView = Backbone.View.extend({
    initialize: function() { 
      console.log('Initializing AboutView');
    }
  });

  var AppRouter = Backbone.Router.extend({
    routes: { 
      "": "index", 
      "about":"aboutView"
    },

    events: function () {
      $('a').click(function (e) {
        e.preventDefault();
        SearchApp.navigate(e.target.pathname, true);
      });
    },

    initialize: function(){
      console.log('Initializing app');
      this.events();
      this.HomeView = new HomeView();
    },

    index: function(){
      this.HomeView = new HomeView();
    },

    aboutView : function() {
      this.AboutView = new AboutView();
    }
  });

  var SearchApp = new AppRouter();
  Backbone.history.start({pushState: true});

});

The identifier id in your tag is not valid. Consider using the following alternative:

<h1><a id="home" href="/">Home</a></h1>
