jQuery Grid Plugin - jqGrid

Hi,

some minor bug in search dialog after reseting search:

$("#kasa_month_list").jqGrid({
url:'go.php?mod=kasa_month&act=list',
rowNum:Math.round(($('#mainContent').height()-160)/20),
colModel:[
{name:'date',index:'date',label:'Data',sortable:false,stype:'date',searchoptions:{sopt:['bw','bn']}},
{name:'users_id',index:'users_id',hidden:true,label:'User',stype:'select',searchoptions:{sopt:['eq','ne'],searchhidden:true},editoptions:{value:'1:Tomas;2:Dmitrij;3:Natalija;5:Eleonora;10:Forumas;12:Romas;'}},
{name:'payd',index:'payd',hidden:true,label:'Payd',stype:'select',searchoptions:{sopt:['eq','ne'],searchhidden:true,attr:{title:'xxx'}
},editoptions:{value:'1:Per kasa;2:Pavedimu;3:I skola…;4:Kortele'}}, ],
mtype:'POST',sortable:false,altRows:true,datatype:'json',height:'auto',autowidth:true,view:true,forceFit:true,rownumbers:false,multiselect:false,viewrecords:true,editurl:'go.php
mod=kasa_month',viewsortcols:false,loadComplete:reinit_thickbox,
}).navGrid('#kasa_month_pager',{edit:false,add:false,del:false,search:true,view:false,excel:false,},{jqModal:false,closeOnEscape:true,afterSubmit:fn_afterSubmit,},{jqModal:false,closeOnEscape:true,afterSubmit:fn_afterSubmit,},{},{jqModal:false,closeOnEscape:true,multipleSearch:true,},{jqModal:false,closeOnEscape:true,afterSubmit:fn_afterSubmit,},{jqModal:false,closeOnEscape:true,});

push button 'search', then in Data field input something, press '+' (multiple search), then select User field and select something, 
aggain press '+' and select Payd field and select something. Do filtering. Press Reset. 
Now we have field Data with selectable searching field instead of normal input field. 

version 3.7.2

And I`m may be wrong of using title in searchoptions (attr:{title:'xxx'}), but this title does not appear in search dialog.
