Title: Prevent multiple load executions.

When setting the `src` attribute to `javascript:false;` in the `cleanUp` method, another `load` event is fired. As a result, the handler that finishes the request is fired again. To prevent this, we can use `jQuery#one` to allow only one execution of each `load` handler.
