jQuery Grid Plugin - jqGrid

Ok, strange problem...

I have a field (2 to be exact...) that a user can fill and after that he can press search, and the jqgrid will start with data of the values entered...

My problem is: I am filling the default Value , and the data is ok, but on the first run the search is not performed.

If I press enter on the toolbar all is great, but not on the opening.

Here is my code:

function jsLoadGrid(){

//jQuery("#list2").jqGrid();

jQuery("#list2").GridUnload();

gridimgpath = "../styles/images";

var mygrid = jQuery("#list2").jqGrid({

datatype: 'json',

url: 'ItemTB.php', //?SearchId='+$("#itemNumber").val()+'&SearchDesc='+$("#description").val(),  //call index.php to fill the jQuery

mtype: 'GET',   

cache: false,

height: '350',     //table

//search:true,

//rowList:[10,20,30,40,50],

{/literal}

colNames:['{$translation->LBL_OrderLineHandler_ITEM_NUM}',

 '{$translation->LBL_CustTOrderHeader_DSC}',

 '{$translation->LBL_OrderLineHandler_CODE_STOCK}',

 '{$translation->LBL_OrderLineHandler_PRICE}',

 '{$translation->LBL_OrderLineHandler_P_SIZE}',

 {foreach from=$warehouseList item=warehouse}

'{$translation->LBL_OrderLineHandler_Warehouse} {$warehouse}',

 {/foreach}

 

 ],

{literal}

colModel:[

{name:'ICAT',index:'SearchId', width:120,search:true,stype:'text',  sortable:false,searchoptions:{defaultValue:$("#itemNumber").val()}},

{name:'IDSCO',index:'SearchDesc', width:280,search:true, sortable:false,searchoptions:{defaultValue:$("#description").val()} },

{name:'ICS',index:'ICS', width:80,search:false, sortable:false},

{name:'IPRC1',index:'IPRC1', width:90,align:"right",search:false, sortable:false},

{name:'IPACK',index:'IPACK', width:70, sortable:false,search:false}, 

 

{/literal}

{foreach from=$warehouseList key=k item=warehouse}

{if $warehouse neq ''}

{literal}{{/literal}name:'IQTY{$k+1}',index:'IQTY{$k+1}', width:100,align:"right",search:false, sortable:false{literal}},{/literal}

{else}

{literal}{{/literal}name:'IQTY{$k+1}',index:'IQTY{$k+1}', width:100,align:"right",search:false, hidden:true, sortable:false{literal}},{/literal}

{/if}

{/foreach}

{literal}

],

pager: jQuery('#pager2'),

imgpath: gridimgpath,

multiselect: false,

gridview : true,

gridModel: true,

autosearch: true,

//searchOnEnter: true,

stringResult: true,

//toolbar : [true,"top"], 

onSelectRow: function(id) {

$("#itemNumber").val(id);

$("#description").val($("#list2").getCell(id,"IDSCO"));

$('#modal').dialog('close');

},

altClass: 'tableCol2',

altRows: true,

autosearch:true,

search:true,

scroll: 1,

jsonReader : { root: 'rows', page: 'page', total: 'total' , records: 'records' }

});

$('#list2').setGridParam( { search:true});

jQuery("#list2").jqGrid('navGrid','#pager2',{edit:false,add:false,del:false,search:false,refresh:false});

jQuery("#list2").jqGrid('navButtonAdd',"#pager2",{caption:"Toggle",title:"Toggle Search Toolbar", buttonicon :'ui-icon-pin-s',

onClickButton:function(){

mygrid[0].toggleToolbar()

} 

});

jQuery("#list2").jqGrid('navButtonAdd',"#pager2",{caption:"Clear",title:"Clear Search",buttonicon :'ui-icon-refresh',

onClickButton:function(){

mygrid[0].clearToolbar()

} 

});

jQuery("#list2").jqGrid('filterToolbar', {gridModel:true , autosearch:true});

//$("#list2").triggerToolbar();

jQuery("#list2")[0].triggerToolbar();

}

The triggerToolbar was the last attempt, but there is no change (and I dont see the additional request made to the server...)

Please help
