Hi Sunny,
The checkbox requires a boolean variable, so you'll have to add a boolean field to the list set as datasource for the Editable Table. You may need to use a temporary list based in a Structure with this extra boolean field as your datasource (in your preparation you would copy the REST resulting list to the temporary one and use this as the datasource).
