Parse.com Save Object Error - edit

Question

Running into issues when trying to edit an object in Javascript.
Getting a "Error 201: must have user password."
Tried to get the users password and couldn't succeed. Trying to edit the users username in my application
function editProfile() {
Parse.initialize("", "");
var ProfileEdit = Parse.Object.extend("User");
var profile = new ProfileEdit();
var currentUser = Parse.User.current();
profile.save(null, {
success: function(profile) {
profile.set(currentUser, $("editprofile-username"));
profile.save();
},
error: function(user, error) {
alert("Error: " + error.code + " " + error.message);
}
});
}

I guess you want to do something like the code I wrote, however I don't understand why are you are using save() two times, maybe I am not really getting the question. . .
function editProfile() {
Parse.initialize("", "");
var currentUser = Parse.User.current();
currentUser.set("username",$("editprofile-username"))
currentUser.save(null, {
success: function(user) {
},
error: function(user, error) {
alert("Error: " + error.code + " " + error.message);
}
});
}
