How do I implement different ToolbarItem for every new page without using custom renderer?

Question

<ContentPage.ToolbarItems>
        <ToolbarItem Text ="Item 1"  
                Priority="0" Order="Primary" />
        <ToolbarItem Text ="Item 2"  
              Priority="1" Order="Secondary" />
</ContentPage.ToolbarItems>

I have a toolbar on the mainpage, from where I navigate to this secondary page. However I am not able to display the ToolbarItems on this secondary page.
