How to bind widgets to google map
I've seen that some Google map widget properties are bindable but I don't understand how.
I want to bind a checkbox to "Show region" property so that I can choose runtime weather show or not my regions; or I want to bind a slider to the opacity in order to change the opacity of the region while runtime.
The thing is, if I change the value of the widget, nothing happens on the google widget unless I refresh the page.
