QML-Get tableview cell content

[neda]

Hi.
I have a TableView with 3 columns (column 1=checkbox, column 2=X and column 3 =Y ).
I want to get cell content of selected row (checked checkbox in column 3 of row).
Immediately after checking checkbox draw a circle in specefic position (x,y).

Model of tableview is QStandardItemModel.

Code:

Canvas {
                                    id: canvas
                                    anchors.fill: parent
									onPaint: {
									var ctx = canvas.getContext("2d");
                                        ctx.globalCompositeOperation = "source-over";
                                        ctx.lineWidth = 1;
										for(var i=1;i<=tablemodel.rowCount;i++){
                                            console.log(tablemodel.model.get(i).XData);
											console.log(tablemodel.model.get(i).YData);

Canvas {
                                    id: canvas
                                    anchors.fill: parent
									onPaint: {
									var ctx = canvas.getContext("2d");
                                        ctx.globalCompositeOperation = "source-over";
                                        ctx.lineWidth = 1;
										for(var i=1;i<=tablemodel.rowCount;i++){
                                            console.log(tablemodel.model.get(i).XData);
											console.log(tablemodel.model.get(i).YData);

To copy to clipboard, switch view to plain text mode 

I have this error:
TypeError: Property 'get' of object QStandardItemModel is not a function

Please guide me
