jQuery Grid Plugin - jqGrid

We have developed grid using jqgrid(4.3.2) with 20 coulmns. First four columns are frozen and last column is hidden. Last but one column is editable checkbox (using inline edit), see below snippet from colmodel,

***{name:'carryoverToNextYear',index:'carryoverToNextYear', sortable:true, search:false ,width:60,align:"center",editable:true,edittype:'checkbox', editoptions:{value:"true:false"},formatter: "checkbox"}*** 

onSelectRow, we are making the selected row editable and previously selected row is restored or saved based on condition.See below code snippet each of the function.

Edit Row code: $("#ciList").jqGrid('editRow', id, false); 
Restore row:$("#ciList").jqGrid('restoreRow',editrowId) ; 
Save Row: $("#list1").jqGrid('saveRow', editrowId )  

First time when I click on any one row it becomes editable, but subsequent row clicks(after calling either restore or save), grid becomes not editable meaning when I click on any other row onSelectRow is not called. Please help.

Note: Also everything seems to work fine when I remove the frozen columns. Also I know inline editing does not work for frozen columns and one column I am talking about is non-frozen column.
