jQuery Grid Plugin - jqGrid

When a row is saved, i want to call this url:

/schedule_entries/:id

where :id is the value of the first column (which is called id).This is a hidden column and is also set to uneditable.  This first column also has key: true in it's options.

I feel like this should be simple, but when i send the request, the only parameters passed through are the row's position number (eg 1 for the first row in the table), in an 'id' parameter, and the contents of the cells in columns set to editable.

I've tried various experiments with the saveRow function, but can't work it out, can anyone help?

thanks
