Updating column that belongs to fixed columns (using extension fixed columns)

Hi, i'm currently working with fixed columns extension and would like to update the column which belongs to fixed columns..the display doesn't show the updated value, as seen on my sample below:

is there a way to render the updated value in the fixed column? thanks in advance...
