How to disable buttons in webgrid after saving data with jquery

I have a webgrid where a list of information is entered, but I give user the ability to delete item in the list by adding a delete button along side each item or in each line. After I post the information to the server the ability to remove item from the list should not be allowed, since the list is already posted, I want to disable all buttons.

 

I have use jquery but only the first button in the list get disabled.

 

Any idea?

 

thank in advance
