Can you please update the commit message according to our guidelines: https://github.com/angular/angular.js/blob/master/CONTRIBUTING.md#commit-message-format

@Narretz
is it ok?
or anything else is needed?
thank you

[Narretz]

Not quite, sorry. In the commit message, you should write "refactor" instead of "fix".
And ofr the future, make sure that there are no merge commits on the branch (i.e. amend the commit instead)

[deplay]

@Narretz
I will delete this refactor branch after merge.

@deplay, as @Narretz said, it makes things easier for us (and hopefully you), if the change was on a single commit with the appropriate commit message.
Something to keep in mind for the next time 😃

@gkalpak Thank u for your suggestion.
also @Narretz ,thank you for your patient reply on this PR.
I will follow the rules in later contributions.
