You could try to instantiate your model object like:

include_once('path/modelname.php');
$home_model = new Home_model();
$home_model->set_where(....);

make sure your model extends de default CI model class.

You could also use $CI->load->model(modelname); instead of include... It's easier to deal with path problems, however it would be a little less efficient because load->model will instantiate an object.
