Allowing a user to change their password using EditTextPreference?

I've got a settings fragment which allows the user to change a bunch of information (such as their password), and I'm using a PreferenceScreen in a separate xml file titled preferences.xml. When I launch the Fragment and go to the Preferences, it allows me to enter values (such as a new password) in the default alert dialog that pops up for EditTextPreference and the data also saves correctly. I checked this using the File Explorer in DDMS to confirm this.

The trouble I'm having is actually getting a reference to that specific EditTextPreference and actually saving the new password.

The EditTextPreference for password looks like

  <EditTextPreference
        android:key="change_password_key"
        android:title="Change Password"
        android:inputType="textPassword"
        android:persistent="true"/>

I don't know how to reference this attribute in my SettingsFragment however.

my SettingsActivity:

public class SettingsActivity extends PreferenceActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getFragmentManager().beginTransaction()
                .replace(android.R.id.content, new SettingsFragment())
                .commit();
        mSharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);

    }

    public static class SettingsFragment extends PreferenceFragment {
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.xml.preferences);

        }

        public void onClick(DialogInterface dialogInterface, int which) {
            switch (which) {
                case DialogInterface.BUTTON_POSITIVE:
                    ParseUser currentUser = ParseUser.getCurrentUser();
                    currentUser.setPassword("change_password_key");
                    currentUser.saveInBackground();
                    break;

                case DialogInterface.BUTTON_NEGATIVE:
                    break;
            }
        }
    }
}
