jQuery Grid Plugin - jqGrid

I think there's a bug. I used the jqGrid 4.2.1, but the problem is in the version 4.3.1, too.
I have a filterToolbar with a select item. I have 3 types of status:

name: Open
value: 38

name: Closed
value: 39

name: Other
value: 40

I have set the colMod like this:

colModel: [ ...
{
 name: 'status',
 label: 'Stato',
 width: 90,
 stype: 'select',
 searchoptions: { value: {'null':'','38':'Open','39':'Closed','40':'Other'}  , defaultValue: '38' }
},

I initialize the value associative array with the couples value-name, like in the wiki guide "If set as object it should be defined as pair name:value. editoptions:{value:{1:'One',2:'Two'}}" (Attention, maybe the problem is here, in the initialization of the select input. cause the documentation says name:value, but in the example there's value:name. However I follow the example, and it shows the select ok).
And it creates this, that is ok, the default value is selected correctly when the page is open.

<select id="gs_status" style="width: 100%;" name="status">
<option value="null"></option>
<option value="38">Open</option>
<option value="39">Closed</option>
<option value="40">Other</option>
</select>

But when I click the refresh button there's a problem.
I checked the code, refresh method call the clearToolbar() that it controls all the toolbar columns.
When it has to check the select input it does this (I debug my case):

$("#gs_"+$.jgrid.jqID(this.name)+" option",(this.frozen===true && $t.p.frozenColumns === true) ?  $t.grid.fhDiv : $t.grid.hDiv).each(function (i){
if(i===0) { this.selected = true; }
 if ($(this).text() == v) {    //this is wrong, because in my case $(this).text is equal to 'Open' and v is equal to '38'. so the 'if' always fails!! and it does not update the selected item correctly.
  this.selected = true;
  v1 = $(this).val();
  return false;
 }
});

if I change, in jquery.jqGrid.src.js file (cause I used this file in my project), the line code

line 3529: if ($(this).text() == v) {

to this

line 3529: if ($(this).val() == v) {

It works well, the if condition is correct and it does what it has to do.

Is that a bug right?
