jQuery Grid Plugin - jqGrid

The onClickSubmit event is not firing and I can't see why. Any help appreciated!

$("#order_hist").jqGrid({ url:'order.aspx?custid='+0, datatype: 'json', mtype: 'GET', colNames: [

'Order ID','Order Date','Order Status','Quantity','Vintage','Display Name','Price','Total'

],

colModel: [ {name:

'orderID', index:'orderID'

, width:75},

{name:

'orderDate', index:'orderDate'

, width:90},

{name:

'orderStatus', index:'orderStatus', width:120,editable:true,edittype:'select',editoptions: {value: "SC:Shopping Cart;P:Picking;SH:Ship Hold;F:Fulfilled"

}},

{name:

'quantity', index:'quantity'

, width:70},

{name:

'vintage', index:'vintage'

, width:60},

{name:

'displayname', index:'displayname'

, width:250},

{name:

'price', index:'price'

, width:60},

{name:

'total', index:'total'

, width:60}

],

onClickSubmit :

function

() {

alert(

'in onClicksubmit'

);

var

retarr = {};

var sr = $("#order_hist").getGridParam('selrow'

);

rowdata = $(

"#order_hist"

).getRowData(sr);

retarr = {orderID:rowdata.orderID};

return

retarr;

},

pager: $(

"#order_hist_pager"

), rowNum:10, rowList:[10,20,30],

sortname:

'orderID', sortorder: "orderID", viewrecords: true, imgpath: 'images/grid_images'

,

caption:

"Order History",height:"150px",editurl:

'order.aspx'

});
