jQuery Grid Plugin - jqGrid

Im building an application in MVC and using JqGrid for my Footballrecords. Two score fields should be editable which are set on null by default from the database, then when the user fills the two score fields he should click on "Save" to post them to the controller. Right now I managed to save the values in the clientarray when leaving the textfields and post the values to the controller when clicking on the save button. The problem now is that after clicking the "Save" button the gridview scorefields are emptied, but I want to keep the inserted values in the scorefields after I pressed the "Save" button. Is there anyone who knows how to keep the inserted values in the grid after saving?
