State won't change when using Dispatcher for checkbox events

[TrackLight (BrainCloud)]

Hi friends – I am using the event dispatcher for the first time, and I ran into a problem that I can’t figure out.

Overview of what im doing: Add list of attachment to a combo box [using checkboxes] that onCheck → they give equipment to player.

What went wrong: Currently the checkboxes bind correctly. But when I check the checkbox, only the value of what I checked prints into logs. (which is a good thing). If don’t hook up the checkbox to current combobox. The current buttons work as expected. Its only not working when I covert them to checkboxes.

Here is the blurprint for it.

1. Created a Check box Widget
   

   
   
   
   

2. Bind to GiveEquipment Widget
   

   
   
   
   

Thanks in advance.

One more thing: Im using the following on selection change to store the value by index. Combo Box Non Optic is the main combo box that lists the buttons that I wanted to convert to check boxes.
