Evaluating controller property everytime the template is rendered in Ember - ember.js

Question

I have a template called sample and I am changing the property show in the controller based on a button press. Now I want the controller to reset the property every time the template is rendered. Currently even if I go to 'next' template and come back, the property show remains true if the button on sample was pressed. I want to change this behaviour and the property show should be false by default. I know I can do this by defining a view and using the didInsertElement hook but is that the only way to do this?? Ember.js website says that Views in Ember.js are typically only created for the following reasons:
When you need sophisticated handling of user events
When you want to create a re-usable component
and I am doing none of the above. Here is some sample code:
<script type="text/x-handlebars" data-template-name="sample">
{{#if show}}
Showing stuff
{{/if}}
<button {{action changeShow}}>Change</button>
{{#link-to 'next'}} Next {{/link-to}}
</script>
<script type="text/x-handlebars" data-template-name="next">
Hello
{{#link-to 'sample'}}Back{{/link-to}}
</script>
App.SampleController=Ember.Controllers.Extend{(
show:false,
actions:{
changeShow:function(){
this.controllerFor('sample').set('show',true);
}
}
)};

Answer 1

you can use didTransition action which will trigger automatically once the transition happened. didTransition action
App.SampleController=Ember.Controllers.Extend{(
show:false,
actions:{
didTransition:function(){
this.controllerFor('sample').set('show',false);
},
changeShow:function(){
this.controllerFor('sample').set('show',true);
}
}
)};

You can use the renderTemplate hook for the route you're doing this in, and change the controller variable in there.
http://emberjs.com/api/classes/Ember.Route.html#method_renderTemplate
I'd do something like this:
App.PostsRoute = Ember.Route.extend({
renderTemplate: function(controller, model) {
var favController = this.controllerFor('favoritePost');
favController.set("toggle", false)
this._super()
}
});
