How to properly update a row after the update button is clicked (and a json response comes back with the data to be updated)?

[Andrew]

When I edit a bunch of fields in a row, I click update and it sends the data to my php server. The php server sends back some json data and I want the same row to update.

For example:

I update a row and it has some fields in it like projectscore, adjustment and weight. The server saves the data and sends back the project total so it can be properly updated in the table. right now this is the json postback
{"id":"1","ptotal":75}

id is the id of the row (specified in the table, this is working), and ptotal is the column name of the column I need updated

How do I update the column in the table from the response from the server after an update or a create?

This is a server side php, client side kendo system (the table is a nested table in a hierarchy setup)

I see that the inline response in the demo is 
"jQuery18209422706338401393_1363880656837([{"ProductID":78,"ProductName":"aaa","UnitPrice":4,"UnitsInStock":2,"Discontinued":false}])"

My response right now is:
[{"projectId":81,"projectname":"test12","projectscore":"81","adjustment":"0","weight":"80","completiondate":"2013-03-21","ptotal":5}]

what is "jQuery18209422706338401393_1363880656837()" do I need it and where does it come from? the table keeps duplicating data and the return ID never gets assigned to the new record generated (or the rest of the variables dont update either)

Took me awhile but I had to change my response to this:
{"d":[{"projectId":"1","projectname":"test project1","projectscore":"71","adjustment":"1","weight":"100","completiondate":"2013-03-21","ptotal":72,"tscore":"61"}]}

and my data bound to "d" and it worked
