Refreshing toolkit:listpicker after database update

Question

I have toolkit:listpicker in my windows phone 8.1 app mainpage.xaml

<toolkit:ListPicker x:Name="ListPicker"
                    HorizontalAlignment="Left"
                    Margin="40,10,0,0"
                    VerticalAlignment="Top"
                    Grid.Row="1">
    <toolkit:ListPicker.ItemTemplate>
        <DataTemplate>
            <toolkit:ListPickerItem Content="{Binding ListName}" />
        </DataTemplate>
    </toolkit:ListPicker.ItemTemplate>
 </toolkit:ListPicker>

and another page that add's item in local database. When i add item, listpicker is not refreshed until i close app and reopen it again.

Can someone help me with this?

Implement the Inotifypropertychanged pattern on your datasource. That way the UI wil respond to any changes you make in your datasource.
