bugs in setting toggle button value in the Addins -> Toggle button version 2.5.0

[studamits]

Actually I have noticed bugs in the Addins -> Toggle Button Widget

1. Set value and get value: When you try to set some values to ToggleButtons with function setValues and option multiple = true, then when you try to get values nothing comes out from the function getValues().
2. When activating multiple toggle buttons with setValues, then I need to click twice to de-activate the selected toggle options
