AEM forms AEMaacs - unable to retrieve data from repeated panels

Hi all,

I am working towards creating custom repeated panel as shown below using the AEM form core components and AEM core component blank template. Given this , 

I used the functionality within accordion of adding removing panels and I get no value despite trying fieldname[0] or panel.instances[0].fieldname 

anyone tried this ? 
I didn want to use the repeated section setting min max alone without script cause then I won’t be able to give authors chance to click the add or remove button 

kindly let me know if I am missing something
