I have upgraded the jgrid from 3.7.2 to 4.4.4 from then onwards getRowData(rowId) is not working (ie not returning the row details)

my corresponding code snippet is

=======================================================

subGridRowExpanded: function(subgrid_id, row_id)

{……..

var temprecord = new Array();

temprecord = jq(“#dataGrid”).getRowData(row_id);
