How to refresh widgets content without reloading page?

Hi there,

We created a specific structure of widgets on users profile page,
content and information inside some of this widgets could be changed
dynamicly and some time we need to refresh on of them. There are only
two ways to refresh widgets content. On of them is refresh a whole
page, another one is open widget's settings and clicking on Save

So may be is a good idea to add some refresh button beside setting's
button and close button at the widgets header.

What do you think about this?
