Ember.js {{action}} other than click

Lets say I have a template with several button elements in it. If I want to watch for a click event then I just use the {{action}} helper. But I can't figure out a way of passing other events like mouseEnter or mouseLeave. I would have thought to use Ember.Button and somehow do it through childViews but it seems to be deprecated.

template

{{#view App.MyView}}
    <button {{action "btnClicked"}}>button1</button>
    <button {{action "btnClicked"}}>button2</button>
{{/view}}

js

App.MyView = Em.View.extend({
    btnClicked: function(e){
       alert('btnClicked');
    },
    btnMouseEnter: function(e){
       alert('btnMouseEnter'); // how to call this?
    }
});​

I know I can use {{action "btnMouseEnter" on="mouseEnter"}} but then I lose the click functionality. Do I need to wrap each button in its own Ember.View? If so, why was Ember.Button deprecated?

Edit:

I think you should be be able to have multiple events trigger the same action

<button {{action "myAction" on="click mouseEnter mouseLeave"}}>button</button>

I implemented this behavior in my fork and here is a jsFiddle demonstrating it working

Edit:

if someone is also interested in this functionality, the discussion is going on here.
