The following code changes the caption of a button and the contents of a html element.
this.scope.buttonStart.options.content = "MyText"; this.scope.customhtml0.options.html = "MyText";
The code is working for the button but the html element doesn't update its text.
I tested this and both the button and the HTML element were updated.
Here is a link to my test app:
I hope this helps.
The code to change the text of the custom html component is in the 'Change Event function' of a date picker.
As said earlier, the text isn't updated, but alert(this.scope.customhtml0.options.html) shows the updated text in a popup.
It seems that the custom html component needs a refresh/repaint command.
