javascript inside InfoWindow

javascript inside InfoWindow

I'm having this issue I would like to open an InfoWindow to which I set a
given html content as a string but it happens that this html content has
some JavaScript functions that needs to be executed when the HTML is
rendered inside the google.maps.InfoWindow object.
Is there a way to do that?
for more details, the concrete case is this. As part of my html string I
have a javaScript function for rendering graphics from
google.visualization. API therefore in my java script y set the content to
the infowindow in this way.
myHtml = 'html code with java script function fro rendering
google.visualization......';
info = new google.maps.InfoWindow()
info.setContent(myHtml)
as a result, I can correctly see the HTML rendered inside the InfoWindow,
but without the graphs rendered.
is there another way to do this? I've tried it in different browsers with
no possitive results.
thanks in advance.
