I set stroke

new go.Binding(“stroke”, “textColor”, this.bindShapeTextColor),

I change textColor color from my color palette but bindShapeTextColor not firing.

no function is called
Why?

                         goMake(go.TextBlock,
                            {
                                editable: true,
                                stroke: "black",
                                font: "6pt sans-serif",
                                verticalAlignment: go.Spot.Center,
                                alignment: go.Spot.Center,
                                margin: new go.Margin(1, 5, 0, 5)
                            },
                            new go.Binding("stroke", "textColor", this.bindShapeTextColor),
                            new go.Binding("font", "textFontName", this.bindShapeTextFont),
                            new go.Binding("isUnderline", "textIsUnderline", this.bindShapeTextUnderline),
                            new go.Binding("background", "textBackgroundColor", this.bindShapeTextBackgroundColor),
                            new go.Binding("textAlign", "textIsItalic", this.bindShapeTextAlignment),
