When I use
```
val myProperty = SimpleObjectProperty("My Data")
myTableColumn.setCellValueFactory { myProperty }
```
It just shows `My Data` text in corresponding column cells. I feel like I'm missing some logic on these observable properties. If properties implement `Observable` interface, then there should be some benefit from it. I thought that observable properties after being used by `setCellValueFactory` should be automatically updated when I change a text in the cell, or update a text in the cell, when I change property value, but this does not happen. What's wrong with it?
