SfDropDownList using SfDataManager with EnableCaching="true" not caching as I thought

Question

I have the following dropdown list controls in my view:

<SfDropDownList TValue="Guid?" TItem="DisplayValueResponse" Value="@row.AnswerId">
   <DropDownListEvents TValue="Guid?" TItem="DisplayValueResponse" />
   <SfDataManager Url="@PossibleAnswersUrl(row)" Adaptor="Adaptors.WebApiAdaptor" EnableCaching="true" />
   <DropDownListFieldSettings Text="Display" Value="Value" />
</SfDropDownList>

Here are some of the network calls being made to the server to populate the individual lists:

...api/possibleanswers?&questionId=76be3a3a-6d4d-4098-a4f…e7&versionId=a209fdd0-baf1-48dd-8ba8-df160acba276
...api/possibleanswers?&questionId=017faf57-c816-42aa-888…cb&versionId=a209fdd0-baf1-48dd-8ba8-df160acba276
...api/possibleanswers?&questionId=2184b434-2a7f-4ffa-9f3…f7&versionId=a209fdd0-baf1-48dd-8ba8-df160acba276
...api/possibleanswers?&questionId=70dad0aa-b017-418f-987…97&versionId=a209fdd0-baf1-48dd-8ba8-df160acba276

When the user hits this page again, I was expected those calls to be ignored for the same query string parameters. Do I have it set up wrong or am I under the wrong impression on how caching works?

Thanks,
