Description of Issue

I'm displaying a dataframe, and trying to edit it. I get the following error:
ValueError: At based indexing on an non-integer index can only have non-integer indexers

Reproduction Steps

In a notebook:

data = [[0, 28108, 'blah1', 'asd', 6, 0.6093999743461609, True],
 [1, 23277, 'blah2', 'dfg', 47, 0.5604000091552734, True],
 [2, 84668, 'blah3', 'asd', 7, 0.551800012588501, True],
 [3, 171563, 'blah4', 'asd', 8, 0.5310999751091003, True],
 [4, 133630, 'blah5', 'asd', 6, 0.5145000219345093, True]]
df = pandas.DataFrame(data)
grid = qgrid.show_grid(df, grid_options={"autoEdit": True}, show_toolbar=True)
grid

Then, try editing any of the cells. In Jupyterlab, I get a popup: Error occurred while attempting to edit the DataFrame. Check the notebook server logs for more information.. In the console:

[IPKernelApp] ERROR | Error occurred while attempting to edit the DataFrame. Check the notebook server logs for more information.
Traceback (most recent call last):
  File "/home/ubuntu/anaconda3/lib/python3.6/site-packages/qgrid/grid.py", line 1223, in _handle_qgrid_msg_helper
    old_value = self._df.at[location]
  File "/home/ubuntu/anaconda3/lib/python3.6/site-packages/pandas/core/indexing.py", line 1868, in __getitem__
    key = self._convert_key(key)
  File "/home/ubuntu/anaconda3/lib/python3.6/site-packages/pandas/core/indexing.py", line 1915, in _convert_key
    raise ValueError("At based indexing on an non-integer "
ValueError: At based indexing on an non-integer index can only have non-integer indexers

What steps have you taken to resolve this already?

Workaround for now was to manually set my_qgrid._df, but this seems hacky and unlikely to work correctly.
