I found the thing which cause error.
If this option is ENABLED from Jobmonster Setting > Member page, the Forget Password link does not work at front end :<small>
</small>
"Enable Login Using Email <input name="noo_member[register_using_email]" type="checkbox" value="1" /> <small>Enabling this option will remove username and only use email for login/registration."</small>
If this is disabled from the Setting page, the Forget Password link working.
Now the problem resolved if this option DISABLED - "Enable Login Using Email option"
Note: But it should be working for both options enabled/disabled.
Thanks
