scope.$watchGroup is not a function

[anoopsinghbayes]

i have to support angular 1.2.25 application ,i am using ng-sortable 1.3.5 it get the following error
"scope.$watchGroup is not a function",
scope.$watchGroup is supported only for version from 1.3 and above
as per comments in this issue https://github.com/a5hik/ng-sortable/issues/192
ng-sortable should work with all version as in 1.1, 1.2, 1.3, 1.4

Ran into this issue as well updating the library on a v1.2.25 module.
I was able to get around this by removing the scope.$watchGroup call and using individual scope.$watch statements as follows:

scope.$watch('sortableScope.isDisabled', function (newValue) { if (isDisabled !== newValue) { isDisabled = newValue; if (isDisabled) { unbindDrag(); } else { bindDrag(); } } else { bindDrag(); } });
scope.$watch('sortableScope.options.longTouch', function (newValue) { if(isLongTouch !== newValue) { isLongTouch = newValue; unbindDrag(); bindDrag(); } else { bindDrag(); } });

Hope this helps
