How to share model between tow list boxes

Hi ,
I have two list boxes in two views. In one view i'm displaying list box in list view and another view i'm displaying list box in grid view.

Steps :
1) Created view1 with listbox1.
2) Here listbox displayed in listview.
3) Added item to the listbox1 using system model.
4) From menu i want to switch to next view.
5) In View2 i want to display listbox2 with item as it is in listbox1.
6) So i want to share the same model as it is in listbox1.

But i'm not getting the model when moving to view2. So please let me know what is better approach to achieve this.
Also if i'm in to right path then what is the way to share same model in two different list boxes?

Thanks in Advance!!
