You can use $.proxy():
this.element.click($.proxy(function() {
this.someObjectMethod();
}, this));
It returns a function that will always be invoked in the context of the object you specify in the second argument (in our case, the outer this).
$.proxy() also enforces a special case with event handlers: if you pass the original, unproxied method to off() or unbind() later, the proxied handler will be transparently removed even ifthough you did not specify it directly.
