With ST3, it removes $. Attached fix.

[amerkay]

For code-completing say $scope.$on, it removes the dollar "$", making it $scope.on(...). The fix is to have the $ double escaped in "angular-js.sublime-completions". As in: { "trigger": "angular: $on", "contents": "\\$on(${1:name}, ${2:listener})" }
