Trigger an action on the change event with Ember.js checkbox input helper? - ember.js

Question

How can I fire a named action upon changing a checkbox in Ember.js? Any help will be greatly appreciated.
Here is what I have. Checking or unchecking the checkbox has no effect.
Template:
{{input type="checkbox" on="change" action="applyFilter"}}
Controller:
actions: {
applyFilter: function() {
console.log("applyFilter");
}
}

I'd like to post an update to this. In Ember 1.13.3+, you can use the following:
<input type="checkbox"
checked={{isChecked}}
onclick={{action "foo" value="target.checked"}} />

using an observer seems like the easiest way to watch a checkbox changing
Template
{{input type='checkbox' checked=foo}}
Code
foo:undefined,
watchFoo: function(){
console.log('foo changed');
}.observes('foo')
Example

Or you could create your own implementation of the checkbox that sends an action
Custom Checkbox
App.CoolCheck = Ember.Checkbox.extend({
hookup: function(){
var action = this.get('action');
if(action){
this.on('change', this, this.sendHookup);
}
}.on('init'),
sendHookup: function(ev){
var action = this.get('action'),
controller = this.get('controller');
controller.send(action, this.$().prop('checked'));
},
cleanup: function(){
this.off('change', this, this.sendHookup);
}.on('willDestroyElement')
});
Custom View
{{view App.CoolCheck action='cow' checked=foo}}
Example

Post Ember version >= 1.13 see Kori John Roys' answer.
This is for Ember versions before 1.13
This is a bug in ember's {{input type=checkbox}} helper.
see https://github.com/emberjs/ember.js/issues/5433
I like the idea of having a stand-in. #Kingpin2k's solution works, but accessing views globally is deprecated and using observers isn't great.
In the linked github ember issue, rwjblue suggests a component version:
App.BetterCheckboxComponent = Ember.Component.extend({
attributeBindings: ['type', 'value', 'checked', 'disabled'],
tagName: 'input',
type: 'checkbox',
checked: false,
disabled: false,
_updateElementValue: function() {
this.set('checked', this.$().prop('checked'));
}.on('didInsertElement'),
change: function(event){
this._updateElementValue();
this.sendAction('action', this.get('value'), this.get('checked'));
},
});
Example usage in a template ('checked' and 'disabled' are optional):
{{better-checkbox name=model.name checked=model.checked value=model.value disabled=model.disabled}}

For those using Ember > 2.x:
{{input
change=(action 'doSomething')
type='checkbox'}}
and the action:
actions: {
doSomething() {
console.warn('Done it!');
}
}

In Ember v1.13 it can be done simply by creating a component named j-check in my occasion(no layout content required):
import Ember from 'ember';
export default Ember.Checkbox.extend({
change(){
this._super(...arguments);
this.get('controller').send(this.get('action'));
}
});
And then you just call it from your template like this:
{{j-check checked=isOnline action="refreshModel" }}
