SfListView Not Loaded with Data of ObservableCollection Triggered from another SfListView SelectedItem in previous Page


I have one main page with 4 tabbed pages. 2nd page (budgets) has a SfListView, loaded with budget data of the user and when I select one of the item, another page (financials) of the budget is opened in the current tab. 
This (financials) page has a SfListView as well, however it is not loaded/rendered with data. Two page has same structure, I don't struggle with the first budget page. I have also called the financial page directly by sending financialId to page, and the SfListView is rendered with data. 

I am using MVVM for data binding and connected to my API. I have inspired from your EventtoBehavior sample. 
When I debug FinancialPage, I can see that incomeList has records but binding not reflected! 

I appreciate for your help, in advance. 

I am sharing relavant part of my XAML and C# codes

This code statement at the FinancialPageViewModel.cs has worked temporarily as a workaround. 

        public void OnListViewLoaded(SfListView incomeView)
            incomeView.ItemsSource = IncomeList;  

When I wait for a while, go back to BudgetPage and click again an item, the list is not coming, you need to re-try.

However, I still need support about this issue :/
