Re-loading the controller after Navigation ( SAP UI 5)

I have a UI5 Application with (JS View) a few pages & navigation between them. I am using mutual oModels for transfering data ( For example I am choosing some item on 2. page and I am showing the choosen items on 3. page etc.)

My problem is after navigation the Controller will be loaded only once. And I can't update my Models which means my View won't show the latest datas that I've added to oModel .

Is there anyway for me to handle this problem ? How can I manage to reload my Controllers ( onInit lifecycle function etc. )

PS: oModel.refresh(true) on navigation function doesn't do what I need-

If you need to see my code I can add the relevant part

The onInit lifecycle function is only supposed to run once. If your goal is to run some logic every time you enter one of your screens, you should implement a RoutePatternMatched event handler in your controllers.

Use sap.ui.core.UIComponent.getRouterFor(this); to get your router instance and call the function attachRoutePatternMatched to attach your event. You can look into https://openui5.hana.ondemand.com/#/api/sap.m.routing.Router for more details.
