CodeIgniter - How to return Json response from controller

How do I return response from the controller back to the Jquery Javascript?

Javascript

$('.signinform').submit(function() { 

   $(this).ajaxSubmit({ 

       type : POST,

       url: 'index.php/user/signin', // target element(s) to be updated with server response 

       cache : false,

       success : onSuccessRegistered,

       error: onFailRegistered

   });        

   return false; 

});

Data is returned null (blank)!

function onSuccessRegistered(data){

    alert(data);

};

Controller -

public function signin() {

    $arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);    

    echo json_encode( $arr );

}

//do the edit in your javascript



$('.signinform').submit(function() { 

   $(this).ajaxSubmit({ 

       type : POST,

       //set the data type

       dataType:'json',

       url: 'index.php/user/signin', // target element(s) to be updated with server response 

       cache : false,

       //check this in Firefox browser

       success : function(response){ console.log(response); alert(response)},

       error: onFailRegistered

   });        

   return false; 

}); 





//controller function



public function signin() {

    $arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);    



   //add the header here

    header('Content-Type: application/json');

    echo json_encode( $arr );

}
