Known probleme with my small module

Thank you for you help,
I'm using Drupal 7.
I'm trying to get informations from an external website which is "http://www.emploitic.com".
I name the module emploi, I create the form that contains 2 input text "Titre-emploi" and "Ville".
I put it in a block emploi, so the module works and i get the Block, so I can enter my search informations then press the button "rechercher", I can see in the Console that the right url is sent but nothing back, it appears in red but i get OK.
again the code in emploi.module:

/**
  * Implementation of hook_block_info()
  */
function emploi_block_info() {

  $blocks['emploi'] = array(
    'info' => t('Recherche d"emploi'),
    'cache' => DRUPAL_CACHE_GLOBAL,
  );
  return $blocks;
}

/**
  * Implementation of hook_block_view()
  */
function emploi_block_view($delta = '') {

  $block = array();
  $block['subject'] = t('Recherche d"emploi');
  $block['content'] =  drupal_get_form('emploiShowForm');
  return $block;
}

function emploiShowForm(){
    $form=array();
    $form['Titre_Offre']=array(
        '#type'=>'textfield',
        '#title'=>'Titre',
        '#size'=>25
    );
    $form['Ville']=array(
        '#type'=>'textfield',
        '#title'=>'Ville',
        '#size'=>25
    );
    
    $form['#suffix']='<input type="button" id="submetAjaxButton" value="Rechercher"/><div id="Result"></div>';
    
    drupal_add_js(drupal_get_path('module', 'emploi'). "/emploi.js");

    return $form;
}

and the emploi.js:

jQuery(document).ready(function(){
   jQuery('#submetAjaxButton').click(function(){

            jQuery.ajax({
           url: 'http://www.emploitic.com/offres-emploi/',
           data:{
               Titre_Offre:jQuery("#edit-titre-offre").val(),
               Ville:jQuery("#edit-ville").val(),
               option:'com_candidat',
               controller:'search',
               initSearch:'1',
               task:'doSearch'
           },
           success:function(data){
               jQuery("#Result").append(data);
           }
           });
    });
});
