Jqgrid - edit dialog field not clickable - jqgrid

Question

Using simple built in functionality in Jqgrid where if you set the column property editable to true, it should pop up a form with that field text to be editable. Everything is fine except that the form coming up is not clickable.
Please point me what is wrong with this code before I resort to manual custom form.
$('#tblRecipes').jqGrid({
datatype: 'json',
mtype: 'POST',
url: 'ResultsEditorAjax/GetSampleRecipeValues',
editurl: 'ResultsEditorAjax/SaveSampleRecipeValue',
jsonReader: als.common.jqgrid.jsonReader('Analyte'),
colModel: [
{ name: 'Folderno', index: 'Folderno', sortable: false, hidden: true },
{ name: 'Ordno', index: 'Ordno', sortable: false, hidden: true },
{ name: 'Pcupno', index: 'Pcupno', sortable: false, hidden: true },
{ name: 'Taskcd', index: 'Taskcd', sortable: false, hidden: true },
{ name: 'Analyte', index: 'Analyte', label: 'Analyte', width: 10, sortable: false },
{ name: 'OldFinal', index: 'OldFinal', label: 'Old Value', width: 10, sortable: false },
{
name: 'NewFinal', index: 'NewFinal', label: 'New Value', width: 10,
sortable: false, editable: true, edittype: 'text',
editrules: { custom: true, custom_func: als.webview.analyteresults.validateRecipeValue }
