Tooltip is not updating

Hi there,

I am trying to add tooltip in my custom visual. For that I have written follwoing code.

// this if condition is inside update method
if (this.tooltipSettings.show == true) {

                    const tooltipDataItems = [];
                    if (this.tooltipSettings.title != null || this.tooltipSettings.content != null) {
                        tooltipDataItems.push({
                            "displayName": this.tooltipSettings.title,
                            "value": this.tooltipSettings.content
                        });
                    }
                    
                    // adding measure values into array which will be used for show method
                    // following code will only add measure which are part of tooltip data field
                    tableData.columns.forEach((element, index) => {
                        if (element.roles.tooltipMeasures == true) {
                            tooltipDataItems.push({
                                "displayName": tableData.columns[index].displayName,
                                "value": tableData.rows[0][index],
                            });
                        }
                    });

                    this.root.on("mousemove", (e) => {
                        const mouseX = d3.mouse(this.root.node())[0];
                        const mouseY = d3.mouse(this.root.node())[1];

                        this.host.tooltipService.show({
                            "dataItems": tooltipDataItems,
                            "identities": [],
                            "coordinates": [mouseX, mouseY],
                            "isTouchEvent": true
                        });
                    });
                }

I am fetching data from one measure field in which I can add multiple measures and pushing them into an array for VisualToolTipDataItem.

The problem I am having is that the tooltip is not updating unless I refresh the page. See following example.

I added Tax Rate in in blank tooltip data field and I am able to see the tooltip as shown below.Then I added Profit into field but still I can only see Tax Rate on tooltip. See below screen shot

After reloading the whole page, I was able to see both measures on tooltip as shown below.

I used similiar approach to show tooltip in the past and that time it was working but now it is not working properly.

Can anyone tell me what is happening here?
