Custom Visual: Slicer selection display won't stay when page changes. (Visuals will reload)

Hi there,

I developed a timeline slicer. Everything works fine except that I realised the selection display won't stay when I shifted page. I know when page changes, the visual will automatically reload and hence runs the constructor and reset the visual to default state. How can I prevent the reload or set the constructor to reload the previous status? Is it the workaround something to do with bookmarking?
