Problem While hiding column with dynamicly attaching footer


I am using grid and after its loaded i call a function and in that I am attaching it a footer.
After attaching footer I am hiding some columns as per my logic. but after hiding some of my columns footer is not working properly.

When i hide the column the corresponding footer also should be hidden but its not behaving that way.

this image is showing proper output

after i hide one of the columns the below errored grid is shown

Please Reply asap
Thanx in advance.

Unfortunately the issue cannot be reproduced locally.
Please, try to update the version of your grid, if its less then 3.5
