      User: function (user) {
         document.write('Welcome.. To Adglob');
      }
   }
});

Open the actionparam.hbs file created under app/templates/ with the following code −

//passing the 'user' as parameter to a button
<button {{action "User" user}}>Click Here </button>
{{outlet}}

Now you click on the button, the User action handler will be called with an argument containing the “user” model.
