I am writing the registration script where the API is being called in company registration no field and it fetches all the data regarding company and fill it automatically in according field like name, phone no, address etc. So i want to make the script wait until all text-fields are filled with values. I have tried the following script but it doesn't wait and clicks on continue button before all the values are fetched.  

    require "watir-webdriver"
    require "watir-webdriver/wait"

    br = Watir::Browser.new :chrome
    br.goto verification_link

    br.a(:text => "Continue Manually").flash
    br.a(:text => "Continue Manually").click
    br.text_field(:id => "regNumber").flash
    br.text_field(:id => "regNumber").set "03977902"
    br.button(:id => "populatebtn").flash
    br.button(:id => "populatebtn").click

    Watir::Wait.until(10) {br.text_field(:id => "companyName").value.exists?}

    br.select_list(:id => "companyType").flash
    br.select_list(:id => "companyType").select("Limited")
    br.select_list(:id => "nature").flash
    br.select_list(:id => "nature").select("Art")
    br.text_field(:id => "sales_turnover").flash
    br.text_field(:id => "sales_turnover").set "12000"
    br.select_list(:id => "why").flash
    br.select_list(:id => "why").select("Bill Payment")
    br.button(:id => "lookup").flash
    br.button(:id => "lookup").click
    br.button(:id => "continue").flash
    br.button(:id => "continue").click
