update jtable model after filtering

I want to apply the filter to the JTable.

            String text = textField.getText();
            rowSorter = new TableRowSorter<>(tableModel);
            this.getjTable1().setRowSorter(rowSorter);
            this.getjTable1().removeAll();
            if (text.trim().length() == 0) {
                rowSorter.setRowFilter(null);
            } else {
                //String regex = String.format("^%s$", text);
                if(jCheckBoxExtract.isSelected()){
                    text="^"+text+"$";
                }
                else{
                    if(!text.contains(".")||text.contains("$"))text="^"+text;
                }
                RowFilter rowFilter = RowFilter.regexFilter(text, 1);
                rowSorter.setRowFilter(rowFilter);
            }
            this.getjTable1().repaint();   

this code work but now, if I want to get a value in jtable, the model doesn't update. The model use in jtable is always the old model but not the new model after filter.

to get the proper value do this whenever you need the row from the table:

model.getSelectedEntry(table.convertRowIndexToModel(table.getSelectedRow()));
