jQuery Grid Plugin - jqGrid

Is it possible to have edittype assigned based on value of another column? I have the following but it always returns edittype of text.

See the 'requestedchange' column.

<table id="list2"></table>

<div id="pager2"></div>

<script type="text/javascript">

$(document).ready(function(){

var selID = "";

var temp = "";

$("#list2").jqGrid({

editurl:'/QMSWebApp/DCRIndexEditServlet',

height: "auto",

colNames:['Index#','Priority','Drawing#/Rev','Dwg Index#','Source','Requester','Request Date','Requested Change','Assigned To','Reject Request','Reason for Rejection','MngrAccess','EngAccess'],
