performing via onsubmit not working?

Is it just me or is performing a task via an onsubmit on a form not working? But an action that then calls perform works.

Does not work:

<form onsubmit={{perform createApp}}>

Works:

actions: {

  createApp: function() {
    this.get('createApp').perform();
  }

}

<form {{action "createApp" on="submit"}}>

Defining an onsubmit does not prevent the default behaviour from occurring. You’ll need to call event.preventDefault() to get this behaviour.

Alternatively, just use <form {{action (perform createApp) on='submit'}}> which does preventDefault by default.
