foo:bar(...) is syntactic sugar for foo.bar(foo, ...), i. e. that's the "traditional" object-oriented syntax. The . operator only accesses a member of a table as normal, without doing anything special when used in conjunction with a function call, whereas : sets the self argument of the called function.

storyboard:addEventLsitener(a,b) is sugar for storyboard.addEventLsitener(storyboard,a,b).
