If you make the inputText field autoSubmit=true then your valueChangeListener for the field in the backing bean can invoke the "ExecuteWithParams" operation binding after finding it from the binding container.
If you include my EL helper class from here:

Then your backing bean can do:
  // Find the operation binding by name using EL
  OperationBinding b = (OperationBinding)EL.get("#{bindings.ExecuteWithParams}");
  // execute the operation binding
  b.execute();
