Try this:

  .
  . 
  proxy: {
    type: 'ajax',
    api: {
        create: CONTEXT_PATH + '/mvc/odon/create', 
        read: CONTEXT_PATH + '/mvc/odon/list',
        update: CONTEXT_PATH + '/mvc/odon/update',
        destroy: CONTEXT_PATH + '/mvc/odon/delete'
    },
    .
    .

Passing the parameter:

 var storeDiagnostico= down('gridpanel').getStore();//Ext.create('store.odont.DStore');
        storeDiagnostico.getProxy().setExtraParam("idOdontologia", value);
        storeDiagnostico.load();
