bo-hide doesn't work as expected

[yccheok]

Consider the following

<div ng-hide=true>you will not see me with ng-hide = true</div>
<div ng-hide=false>you will see me with ng-hide = false</div>
<div bo-hide=true>you will not see me with bo-hide = true</div>
<div bo-hide=false>you will see me with bo-hide = false</div>

Note, there are no difference between bo-hide=true and bo-hide=false. Both will display the element.
