Change form caption dynamically

WEB TMS WEB Core
1

I have a popup form with an image slider. Each time the WebImageSliderImageChange is executed the caption of the form needs to be changed, e.g.. Self.Caption := 'some caption'.
However, the caption doesn't change.
Any idea how to change the caption dynamically?
