Using filter editor on ListGridFieldType.LINK

I am using showFilterEditor on my ListGrid, and in that grid I have got a field that I set type ListGridFieldType.LINK, and also set linkTextProperty.

Sample:
ListGridField refjournalField = new ListGridField("url","Newspaper");
refjournalField.setType(ListGridFieldType.LINK);
refjournalField.setLinkTextProperty("newsPaperName");

The problem is that when I filter on that field, it's the url itself it filters on, not the newspaper name, which is the one I want to filter on. Is it a way to achive this?
