input_checkox not working in layer_smooths

[tklebel]

Code taken from the documentation for layer_smooths

mtcars %>% ggvis(~wt, ~mpg) %>%
    layer_smooths(se = input_checkbox(label = "Confidence interval"))

There is no confidence interval displayed (expected), checking the box is not changing it (not expected).

I'm using the latest dev version:

Same issue, using R3.2.1 and latest ggvis.
