xamarin ios Tableview is not getting Reloaded when i use MvxSimpleTableViewSource - ios

Question

My table view does not update whenever its source property is changed. The code is as follows:
public override void ViewDidLoad()
{
base.ViewDidLoad();
viewmodel = this.ViewModel as ListViewModel;
viewmodel.PropertyChanged += HandlePropertyChangedEventHandler;;
var source = new MvxSimpleTableViewSource( TableView, LaborCell.Key, LaborCell.Key);
TableView.Source = source;
var set = this.CreateBindingSet<ListView, ListViewModel>();
set.Bind(source).To(vm => vm.LaborTransactions);
set.Apply();
TableView.ReloadData();
}
ViewModel:
public class ListViewModel :MaxRawBaseViewModel
{
public ListViewModel():base()
{
LoadLaborTransactions();
}
private Collection<LaborTransaction> _laborTransactions;
public Collection<LaborTransaction> LaborTransactions
{
get { return _laborTransactions; }
}
public void LoadLaborTransactions()
{
_laborTransactions = DataService.GetLaborTransactions(somenumber);
RaisePropertyChanged(() => LaborTransactions);
}
}
When ever the change in Transactions am calling the tablview.reolad() on propertychanged method. but it is not reloading my tableview
void HandlePropertyChangedEventHandler(object sender, System.ComponentModel.PropertyChangedEventArgs e){
if (e.PropertyName.Equals("LaborTransactions"))
{
TableView.ReloadData();
}
}

Collection<T> does not implement INotifyPropertyChanged. You can verify that in the docs here. You need to change your LaborTransactions property to a collection type that implements INotifyPropertyChanged like ObservableCollection<T> and MvxObservableCollection<T>. You can see that ObservableCollection<T> implements INotifyPropertyChanged here
Change your LaborTransactions as such:
private ObservableCollection<LaborTransaction> _laborTransactions;
public ObservableCollection<LaborTransaction> LaborTransactions
{
get { return _laborTransactions; }
set {
return _laborTransactions;
RaisePropertyChanged(() => LaborTransactions);
}
}
