jQuery Grid Plugin - jqGrid

I have a JqGrid that filters pretty good the elements wehn using advanced search, but does nothing when using the ToolbarSearch. What could be the cause?

There are some code elements:

jQuery("#grild").jqGrid({

"url": '/Devis/PagedList',

"datatype": 'json',

"mtype": 'POST',

"postData": {},

"width": 920,

"height": 300,

"colNames": colNames,

"colModel": colModel,

"pager": jQuery('#pager'),

"page" : 0,

"rowNum": 30,

"rowList": [30, 50, 100],

"sortname": 'CreationDate',

"sortorder": 'desc',

"loadComplete": function () {

var ids = jQuery("#grid").getDataIDs();

for (var i = 0; i < ids.length; i++) {

var cl = ids[i];

var eltid = jQuery("#grid").getRowData(ids[i]).Actions;

var actions;

actions = '<a href="#" onclick="onGridClickEdit(&quot;' + ids[i] + '&quot;);return false;"><img src="/Content/images/icons/edit16.gif" title="Modifier"></a>&nbsp;';

actions += '<a href="#" onclick="onGridClickDelete(&quot;' + ids[i] + '&quot;);return false;"><img src="/Content/images/icons/cancel16.gif" title="Supprimer"></a>&nbsp;';

jQuery("#gride").setRowData(ids[i], { "Actions": actions });

}

},

"viewrecords": true,

"imgpath": '/Content/jqueryui/images',

"caption": "Commandes",

"shrinkToFit": true,

"hidegrid": false

})

.navGrid("#pager", { "edit": false, "add": false, "del": false, "search": true });

<script type="text/javascript">

$(document).ready(function () {

$("#grid").jqGrid('filterToolbar', { stringResult: true });

$(".datepicker").datepicker({

dateFormat: 'dd/mm/yy',

showAnim: ''

});

});

</script>

I mean, the `PagedList` action is not reached when clicking on the <kbd>Enter</kbd> button after filling-in the search toolbar box, but is reached when opening the advanced search "form".
