Kendo UI Grid Edit popup's change update method return values -

the normal way in kendo ui grid update data add edit popup. want is, think change value in text field.in update added switch case , change submit value. add value , return values grid. want when return value , change , show different value in grid.

here example.....

in edit popup has input text field. submit value "a". in update add switch tells if value "a" change submit value 1(number one). submit value , show value in grid "1" not "a". how ???

i think want custom handler. in grid toss in this:

edit: function(e) {onedit(e)}, 

and on top of page whatever logic want do

function onedit(e) {     if (true) {         $("#whatever").text('hello')  //whatever in case field in grid
