Field as Knockout observable

I have a datasource (array) with Knockout observable properties.
I want the grid to display the value of the observable in the grid.

Grid configuration excerpt:
columns: [
                    { field: "Name"}
]

Here, Name is a Knockout observable. But it doesn't work, because the grid expects a normal js property.
Is there a way to get this working without converting all observables back to normal properties?
