I have two problems, the first is: The Quantity Selector don`t set an initial value when he is rendered.
I wanted that when my page is mounted, I get the value from Quantity Selector for the set this value in an page variable, but the value “don`t exist”, only after change the value in input of the Quantity Selector that value is seted.
In isolation mode Isee that the event that call the function for set this value is “Component onChange”, how I do for define this value when the page is created, because I don`t can choose event “Page mounted”?
The second problems is more important: I would like too define this value in page variable whenever the value is changed when the user press the button in the Quantity Selector, but in isolation mode I don`t can define an page variable or an app variable. How to I set the value in page variable or app variable whenever the value is changed by user??
