Try this

//Apply the search
    table.columns().eq( 0 ).each( function ( colIdx ) {
        $( 'input', table.column( colIdx ).footer() ).on( 'keyup change', function () {
            table
                .column( colIdx )
                .search( this.value )
                .draw();
        } );
