using Cucumber with Netzke to call an action in Grid Panel - cucumber

Question

I'm working on Rails(3.1.3) with Netzke(0.7.3).
I very new for Cucumber.
add_account_for_user.feature
Feature: Add Account For User Feature
In order to add login account
As an Administrator
I want to add login account for other role
Scenario: Adding Login Account
When I login as an Administrator
Then I should be on admin page
When I click on 'Administration' button at right upper of page
Then I should see 'Administrator Management'
And I should see 'Add' button in Administrator Management toolbar
When I click on 'Add' button
Then I wait 10 seconds # for check what happen
The problem is at When I click on 'Add' button step.
It pass but not working correctly. (It should fire event onAddInForm)
It's hanging in loading and do not show new windows panel.
my_steps.rb
Then /^(?:|I )click on '(\w*)'(?:|.*)$/ do |label|
click_link_or_button(label)
step "wait for the response from sever"
end
When /^(?:|I )wait for (?:.*)$/ do
page.driver.browser.execute_script(<<-JS)
JS
end

Answer 1

Found the solution!!
The solution is try to collect Component that you use. and then call that action directly.
When /I press 'Add' button in the '(\w*)' grid$/ do |grid_name|
page.driver.browser.execute_script <<-JS
var containerComp = Ext.getCmp("main_container");
var grid = containerComp.down("#"+"#{grid_name.underscore}_grid");
grid.onAddInForm();
JS
end
But I still don't understand why it not call onAddInForm after click.
