Add wp-editor in admin section in wp-job-manager plugin

How can we add wp-editor in textarea in admin dashboard in wp job manager plugin?

Below code working in front end but in back end it is not working

 add_filter( 'submit_job_form_fields', 'frontend_add_salary_field' );


 function frontend_add_salary_field( $fields ) {
 $fields['job']['job_salary'] = array(
 'label'       => __( 'Salary ($)', 'job_manager' ),
 'type'        => 'wp-editor',
 'required'    => true,
 'placeholder' => 'e.g. 20000',
 'priority'    => 7
 );
 return $fields;
 }

For back end i used

  add_filter(job_manager_job_listing_data_fields','admin_add_salary_field'   );


 function admin_add_salary_field( $fields ) {
 $fields['_job_salary'] = array(
 'label'       => __( 'Salary ($)', 'job_manager' ),
 'type'        => 'wp-editor',
 'placeholder' => 'e.g. 20000',
 'description' => ''
 );
 return $fields;
}

This is not working.
