Ember.js map action keyUp event

I'm trying out Ember.js but I'm stuck when using actions.

If I use the following:

<button {{action "test"}}>Test</button>

And create a controller:

App.NewController = Ember.ArrayController.extend({
    actions: {
        test: function() {
            console.log("test");
        },
    }
});

Then everything works fine and I can see test in my log. However, when I try the following:

<input type="text" {{action "test2" on="keyUp"}} />

And define the test2 action in a similar way:

App.NewController = Ember.ArrayController.extend({
    actions: {
        test: function() {
            console.log("test");
        },
        test2: function() {
            console.log("test2");
        }
    }
});

Then it doesn't seem to work. My test button is working, but the keyup event handler is not fired as I expected after reading the documentation.

It looks like there is a bug (or at least very odd behavior) affecting the ability to use actions with keyboard events. Normally, actions handlers for non-keyboard events (like the default "click" event) don't work when modifier keys are pressed. In your code, if you add allowedKeys="any" to your action helper, then your handler will get invoked.

That's really weird, I'll keep looking into it, but you could just use the input helper and observe the value, additionally you could extend the textfield and get the keyup there if you care about which key they are pressing.

{{input value=name}}

  postKey: function(){
    console.log(this.get('name'));  
  }.observes('name')
