The argument to #call: is a method name, not a method call itself. If
you have a look at the generated code with FireBug you can see that
this produces $('#username').focus()(). The methods #call:,
#call:with:, #call:with:with:, etc. are the Javascript counterpart to
#perform:, #perform:with:, #perform:with:with: in Smalltalk.

Another issue -- but that is from my side -- is that #focus is
missing. I will shortly commit a version of JQuery-Core that includes
these event triggers as native methods, so you don't need to use
#call: anymore.
