[Sloved][custom Vtype] form is valid if my field is invalid

[aityahia]

hi all
i have writen an custom Vtype that check if an id already exist,the field is properly marked invalid if it is, but my form still validand can be submited.

there is the code of my validator

Ext.apply(Ext.form.VTypes, {
duplicateId : function (val, field){
var validfield = true;
Ext.Ajax.request({
  url:'rh/getdata',method:'POST',
  async : false,
  params :{gData:'ifExist',matricule: val },
  success: function(responseObject){
   var resp = responseObject.responseText;
       if (resp == 1) {
              validfield=false;
           field.markInvalid('Ce matricule est déja attribué à un employé !');                
         } else if (resp == 0) {
             validfield=true;

          field.clearInvalid();
}},
  failure: function(){return false}});
  
  return validfield;

}
});

i check if form is valid before submiting.

  submit : function ()
    {
        if (this.getForm().isValid())
        {    
    this.getForm().submit({
         url: 'rh/setdata',
      waitMsg: 'Enregistrement en cours...',
      scope : this,
      method: 'POST',
      success:this.onSuccess,
     failure:this.onFailure,
      params: 
     {
      gData : 'saveEmploye',
      newEmp:this.nouvEmp 
     // matricule:idadds
   }})}
   else
   {this.showError('Veuillez completer votre formulaire','erreur');}
    }

I have certainly omitted something

Ext.apply(Ext.form.VTypes, {
  duplicateId: function(val, field) {
    var validfield = true;
    Ext.Ajax.request({
      url: 'rh/getdata',
      method: 'POST',
      async: false,
      params: {
        gData: 'ifExist',
        matricule: val
      },
      success: function(responseObject) {
        var resp = responseObject.responseText;
        if (resp == 1) {
          validfield = false;
          field.markInvalid('Ce matricule est déja attribué à un employé !');
        } else if (resp == 0) {
          validfield = true;
          field.clearInvalid();
        }
      },
      failure: function() {
        return false
      }
    });

    return validfield;// this cause your request valid. because since request ajax so at at that time //we can not say whether the request is success or failure


  }
});
