Can Route model observe applicationController props? - ember.js

Question

I'm building ember app, and I have date selector at the top and a few tabs. Each tab represents a model to work with, but all models need date selector. So I store the date selector values as applicationController properties, and I've reached the point where I need to load data with store.query("Model", {date: applicationController.date}) and now I'm lost. If I use ModelController with hooks like:
export default Ember.Controller.extend({
appController: Ember.inject.controller('application'),
myNeedData: function() {
this.store.findAll('myNeedData',
{date: this.get('appController').get('selectedUrlDate')}
);
}.property('appController.selectedUrlDate')
})
everything actually works, but it is a hack. So I need to load model data through Route's model(). But how can I pass applicationController property to Route and make it observe the changes?

Thanks, Kitler for pointing out the path of researching. So I've made the service
export default Ember.Service.extend({
store: Ember.inject.service(),
loadModel(date) {
// some important actions
}
});
then the controller functions:
export default Ember.Controller.extend({
nextMonth() {
var date = this.get('selectedDate');
date.setMonth(date.getMonth() + 1);
this.set('selectedDate', new Date(date));
},
prevMonth() {
var date = this.get('selectedDate');
date.setMonth(date.getMonth() - 1);
this.set('selectedDate', new Date(date));
},
});
and the route:
export default Ember.Route.extend({
modelService: Ember.inject.service('my-service'),
model() {
return this.prepareModel();
},
setupController: function(controller, model) {
controller.set('model', model);
},
prepareModel() {
const date = this.controllerFor('application').get('selectedUrlDate');
return this.get('modelService').loadModel(date);
},
actions: {
nextMonth() {
const self = this;
self.controllerFor('application').nextMonth();
self.refresh();
},
prevMonth() {
const self = this;
self.controllerFor('application').prevMonth();
self.refresh();
},
}
});
So now I have data manipulation in route, not important repeatable property currentDate and its manipulation in application controller, and route accordingly changes model on user interactions due to refresh!
