Product configurator add new field : Qty

Hi Experts,

In product configurator screen I'm seeing only standard field. I would like to add some new field based on the bookshelf doc and oracle doc but it is not working. I have tried but still not reflecting in the configurator page.

An Example How to Display a New Field in eConfigurator (Doc ID 1931186.1)

We have modified the "eCfgControlComboPriceJS.swt"

Changes:

<swe:for-each id="1100" CfgLoopType="DomainAndChildren" Automation="N" startValue="1000" count="Dynamic" iteratorName="1100Id"

                     Usage="ComboBox"

                     CfgFieldList="CfgFieldName:Name, CfgUIControl:lblName, HtmlAttrib_width:310, Default:Y*

                                   CfgFieldName:RequireMoreChild, Default:Y*
