Uncaught use groupOption() to set groupModel options.

hello!

i try to use this sample http://paramquery.com/pro/demos/group_rows
add toolbar item to reload the grid
{type:'button',
label:'Reload',
listener: function (evt) {
grid.pqGrid( "refreshDataAndView" )
}
}

but,it not work.
 it's error message :Uncaught use groupOption() to set groupModel options.
Is it possible to use grid.pqGrid( "refreshDataAndView" ) on Row grouping? Thank you.

Correct syntax is grid.refreshDataAndView();
