Fix missing and non-working parameters (#8)

* Fix prettify argument not being executed

range.slider's `prettify` param is a function that allows the user to customize the displayed values on the slider.

Currently, it's not being executed, since it's bound as a plain value.

* Added missing parameters from range.slider
