I think you should change it to:

Item {
     id: mainWidget

     // Connect to our dataengine
     PlasmaCore.DataSource {
         id: banksSource
         engine: "skgdataengine"
         interval: 0
         connectedSources: ["Accounts"]
     }

     // Use a modelProxy for easy filtering / sorting
     PlasmaCore.SortFilterModel {
         id: banksModel
         sourceModel: PlasmaCore.DataModel {
             dataSource: banksSource
             /// sourceFilter: "Accounts" // I think this is not needed because you use only one source
         }
     }

     // Put all accounts in a Column
     ListView {
         anchors.fill: parent
         model: banksModel

         delegate: Text {
             text: model["type"]
         }
     }
}
