Here's with Your code.
It's converted, like there was no bbcode at all.
And ofcourse i tried to disable all plugins, but, as i expected, that does not change anything.
With code i've posted somewhere above this BB code works fine, but, as i said, there is problem with apostroph in {param} closing parameter of JS function.
