jQuery Grid Plugin - jqGrid

I used that and found that, but it doesn't work(I can't see the datepicker window) :

jQuery(document).ready(function(){
    jQuery(”#editgrid”).jqGrid({         
       url:'get.php',
    datatype: “json”,
       colNames:['Id','Havuz','Tarih', 'Giren', 'Çıkan','Ortalama','Açıklama'],
       colModel:[
           {name:'id',index:'id', width:40, align:"center"},
           {name:'havuz',index:'havuz', width:90, align:"center", editable:true, editoptions:{size:5}},
           {name:'tarih',index:'tarih', width:80, editable:true, editoptions:{size:10}, sorttype:"date"},
           {name:'giren',index:'giren', width:90, editable:true, editoptions:{size:5}},
           {name:'cikan',index:'cikan', width:60, align:"right", editable:true, editoptions:{size:5}},
           {name:'ortalama',index:'ortalama', width:60, align:"right"},        
           {name:'aciklama',index:'aciklama', width:200, align:"right", editable:true, edittype:"textarea", editoptions:{rows:"2",cols:"20"}}
        ],
    height:260,
    width:600,
       rowNum:10,
       rowList:[10,20,30],
       imgpath: 'themes/basic/images',
       pager: jQuery('#pagered'),
       sortname: 'id',
    viewrecords: true,
    sortorder: “desc”,
    caption:”Yeni Kayıt Ekleme Formu”,
    editurl:”ekle.php”
   
});
$(”#bedata”).click(function(){
jQuery(”#editgrid”).editGridRow(”new”, {addCaption: “Kayıt Ekle”, bSubmit: “Kaydet”, bCancel: “Vazgeç”, processData: “Kaydediyor…”});
    onInitializeForm: function(formid) {
$(”#tarih”,formid).datepicker({dateFormat:”yy-mm-dd”,showOn:'focus'});
}
});
 
});
