The requested URL /drupalhr/drupal/employee/add/ was not found on this server - drupal-7

Question

I have created a custom module in drupal with entities. I have installed the entity api module. I have created my database schema with just two columns (employee_id, first_name) through the help of employee_management.install file (where as employee_management is my custom module name) and employee is my entity name.
I have also written the requisite functions employee_management.module but still it shows me the error , Whenever i tried to add a new entity in the admin/structure/employee it shows me the following error: "Not Found".
The requested URL drupal/employee/add/ was not found on this server.
function employee_management_entity_info() {
$employee_info['employee'] = array(
// A human readable label to identify our entity.
'label' => t('Employee Entity'),
// The controller for our Entity - extends the Drupal core controller.
'controller class' => 'EmployeeController',
// The table defined in hook_schema()
'base table' => 'employee',
// Returns the uri elements of an entity
'uri callback' => 'employee',
// Fieldable that we can attach fields to it - the core functionality will
// do the heavy lifting here.
'fieldable' => TRUE,
// The unique key of our base table.
'entity keys' => array(
'id' => 'employee_id',
),
// FALSE disables caching - caching functionality is handled by Drupal core
'static cache' => TRUE,
// Attach bundles - i.e. alternative configurations of fields associated with a main entity.
'bundles' => array(
'employee' => array(
'label' => 'Employee',
// Information below is used by the Field UI - they "attach" themselves here and lets us
// do the standard field management that all the core entities enjoy.
'admin' => array(
'path' => 'admin/structure/employee/add',
'access arguments' => array('administer employee entities'),
),
),
),
// View modes allow entities to be displayed differently based on context. We simply have one option
// here but an alternative would be to have a Full and Teaser mode akin to node.
'view modes' => array(
'full' => array(
'label' => t('Full'),
'custom settings' => FALSE,
),
)
);
return $employee_info;
}
EDIT
function employee_uri($employee) {
return array(
'path' => 'employee/' . $employee->employee_id,
);
}
And here is the complete list of function in the file employee_management.module

You don't automagically get the route and form to create your entity, you'll have to implement that yourself. See hook_menu and this guide.
