  Solution:
  
  Check Bindings: Review the bindings in your XML view or JavaScript code to ensure that the same object is not being bound to multiple controls within the same UI element.
  Use Unique Instances: If you need to display the same data in multiple places, consider creating unique instances of the object or using a different approach to reference the data.
  Refactor Code: If the design allows, refactor your code to avoid the duplication of the object in the same UI element. This may involve restructuring your data model or the way you are binding data to the UI.
  Debugging: Use debugging tools to trace the bindings and identify where the duplication is occurring. This can help you pinpoint the exact location in your code that is causing the issue.
