when deleting / editing a character in the middle of the masked text, moves the cursor to the end

I had similar issues when I implemented something like from the https://stackoverflow.com/questions/16889502/how-to-mask-an-edittext-to-show-the-dd-mm-yyyy-date-format ... and for the solution of that problem I came specifically on Github searching for similar libraries doing date formatting, The cursor should be in the appropriate place so that user don't have to tap on position again for editing.
