Hi Canis Lupus,
The DataList control doesn't have client-side object so you can hardly fire its events from the client. Why would you want to do that?
By default, the user should click on the insert/update buttons, for example, in order to fire the respective server-side event. You can try to inspect the insert button using a tool like firebug in order to see how the DataList postbacks to the server (I guess it is using the __doPostBack function) and manually call it. However, this sounds like a hack to me, since such events should be triggered by the user. Could you please share what you are trying to achieve?
