Issue with typescript-jquery generator returned promise type

Description

I was not able to use the typescript-jquery bindings in vscode or compile a simple application using them.

    someApi.someMethod().then( (result) => console.log(result.body));

The generated code looks like:

    let dfd = $.Deferred();
    $.ajax(requestOptions).then(
        (data: models.Operation, textStatus: string, jqXHR: JQueryXHR) =>
            dfd.resolve(jqXHR, data),
        (xhr: JQueryXHR, textStatus: string, errorThrown: string) =>
            dfd.reject(xhr, errorThrown)
    );
    return dfd.promise();

While my new-to-the-topic opinion is that it should look more like:

    let dfd = $.Deferred();
    $.ajax(requestOptions).then(
        (data: models.Operation, textStatus: string, jqXHR: JQueryXHR) =>
            dfd.resolve({ request: jqXHR, body: data }),
        (xhr: JQueryXHR, textStatus: string, errorThrown: string) =>
            dfd.reject({ request: xhr, body: errorThrown})
    );
    return dfd.promise();

Given that the signature of the generated method is:

public someMethod(): JQueryPromise<{ response: JQueryXHR; body: models.Operation;  }>

Not sure about the reject part, but both the compiler and intellisense are happier.

Swagger-codegen version

2.3.1 and 2.4.0-20180627.132127-273

Using jquery 3.1.1, with @types/jquery 3.3.4

Command line used for generation

swagger-codegen generate -l typescript-jquery -i ... -o ...

Note

It may very well be that I'm doing something wrong, in which case I'd suggest to maybe add some examples on how to call the generated code (either in a comment of the generated code, or in a separate example).

Start by reproducing the issue with the shown typescript-jquery generation command and inspect the generated method's JQueryPromise declaration and Deferred callbacks. Done means the generated promise's declared result matches its resolved value and the example compiles with the cited jQuery typings and provides correct editor assistance.
