It's a bit hard to follow the code snippet provided, but I would guess that the problem you are seeing is due to the fact that you are recycling the cell and that each time you recycle it you are:

• creating a new cell child view,
• creating a new binding,
• clearing the old child view
• but not removing the old binding.

One way to solve this might be to use the WithClearBindingKey fluent method to allow you to clear these bindings.

For example, if a binding is created as:

 var set = this.CreateBindingSet();
 set.Bind(text).To(vm => vm.TextValue).WithClearBindingKey("MyDynamicBindings");
 set.Apply();

then just the bindings created with this tag can be cleared using:

 this.ClearBindings("MyDynamicBindings");
