ng-disabled not read

[shanedublin]

this busy function overrides the ng-disabled.

if ng-disabled = false then when busy is done, ng-disabled get ignored.

Had the same issue. Just use this instead of ng-disabled:
not-busy-disabled="{{ yourFlagForDisable }}"

UPD: Actually, if you need to change button disable without emitting event you should use both. ng-disabled which will enable disable button on changes of model for example, and not-busy-disabled to get back to the required disable state after "busy" is finished. Of course it would be better that not-busy-disabled were mapped to button disable attribute, then we could use only 1 directive
