Icons in a Grid are old after sorting

[Hari]

Hi,

I have a column in the grid that contains icons.These icons are updated properly on a button click , the latter is outside the grid.
However if I now sort the grid, the icons are not updated. I used  the below code  to update an Icon in a button click event.

$("#Img_" + ModId).attr("src", $.url("Content/images/Active.png")) 

Is this a problem with my code or sort function ? Please let me know.
