I have a problem with my form's submit.
Here is my code

Code:
var WrapperTitleEdit = new Ext.form.TextField({
                    fieldLabel: 'Titre',
                    id:'idtitle',
                    name: 'title',
                    width: 100,
                    allowBlank: true,
                    value: dataItemGrid.title
                });

                var WrapperDescriptionEdit = new Ext.form.TextField({
                    fieldLabel: 'Description',
                    id:'iddescription',
                    name: 'description',
                    width: 100,
                    allowBlank: true,
                    //blankText: 'Une description est requise',
                    value: dataItemGrid.description
                });

                var WrapperLinkEdit = new Ext.form.ComboBox({
