create new instance of itemrenderer in MX DataGrid

I want to create new instance of item renderer for my data grid.

A single instance of your Item Renderer class (ListIR) is created for each visible item of the list-based control.

As the user scrolls through the items of a data grid control, Item Renderer instances are recycled rather than creating new instances.

any idea how to achieve it .

thanks in advance javaamtho

Set useVirtualLayout to false for your list. More information is here.
