I have a button that apply filter to jquery datatable

$("#buttonFilter").button().click(function() {
                if (lboxColor.val() != null) {
                    jqTable.fnFilter($("option:selected", lboxColor).text(), 1);
                }
            });

It shows me for example 47 rows from 60. I tried .fnGetData() and fnGetNodes() but it shows me all rows, but not filtered. How could I get 47 rows?
