BUG: Update of the State name in the dropdown

[fccoelho]

When you change the state in the dropdown menu the name does not change. Then if you do a second change, it changes to the previously selected name.
The visualizations update correctly but the update of the widgets is delayed.

I was testing it here and it seems to be updating very slowly. When we change the state it will update the title first, then each of the graphics and finally the name in the dropdown. @luabida do you have any suggestions as to what should be done?

@eduardocorrearaujo my blind guess would be that the page awaits for the UF (or other parameter) to change, this await (corroutine) is not finished as the parameter is changed again, so meanwhile its loading the second change it finishes the previous one, renders in the page, and the second await finishes on top of it later on. There must be a way of sending a stop signal to the corroutine so it flushes its loading process and start the correct one right away
