JsFunction bind not a function

[lastmjs]

Here's some example code:

  let bound_function = exports_js_object
      .get(&export_name)
      .to_function()
      .unwrap()
      .get("bind")
      .to_function()
      .unwrap()
      .call(&[JsValue::Int(4).into()]);

This code executes just fine as in the unwraps do not panic, but bound_function is an exception and when I dump the error it essentially says this: TypeError: not a function at bind (native).

I am trying to pass some dynamic data into a function created dynamically in Rust, and it seems the only way I can really do this is through the this_val, thus I am trying to set it. A closure will not work because of a wasmwedge-quickjs assertion that seems to panic whenever the JsFunction closure captures any of its environment.
