Hi mpfromindia,
The cells renderer allows you to override the built-in cells display with custom HTML. However, that does not change you cell values and clicking on a cell will not change your cell’s value, too. When you scroll back, your cells renderer implementation will use the old cell value and will display the old HTML string as expected. If you want to implement custom cells editing, that’s something else. You will need to use the Grid’s setcellvalue method for applying new value for your cells.
