Titanium Cloud Email Reset Password Not Working

Hello I have trying to send a reset password email to users in titanium IOS but its not working.

Here is my Code:

Ti.Cloud.Users.requestResetPassword({ email : 'email.value' }, function (e) { if (e.success) { alert('Success: Reset Request Sent'); } else { alert('Password reset fail :' + e.message); } }); });

Your Suggestion is valuable for me. Thanks in advance.
