disabled option is not updated

[avados]

Hi,

My list is observable, and depending on the type, sorting should be disabled or enabled, but it seems that when my boolean is updated, it is not in sortable:

<ul data-bind="sortable: {foreach: layerArray, disabled: layerEditable(), options: { onEnd: stepSwitchPositionEnd , handle: '.dragHandle'}}">

[avados]

I was able to go over this problem setting the css for the handle when needed, but the original issue is still there

I suggested a fix (pull request) in issue #5
