darn. getting an input element to work with event delegation is pretty tricky. I can't .toProperty($("#element").value) because #element doesn't exist yet. I suppose I can merge an obs that essentially emits when the element is visible (such as if the user has clicked a tab in the UI that displays the element) but I was hoping to avoid that.
unfortunately the soft deadline for my project has turned into a hard deadline, so I think I'll have to revert to using what I know instead of kefir :(
