Hook into event when listview is loaded

Does anyone know if it is possible to hook into an event of a specific widget? Concrete example, I am showing a listview with datasource Microflow on the page. This listview takes a while to being retrieved and shown in the page while the DOM of the page is already loaded. Based on the content of the listview, I want to perform certain actions (in this case, activate an input field inside the list). I can write a custom javascript with a setTmeout, but this seems a bit smelly. Is there a way to listen to lifecycle events for widgets?
