Get string value from Bokeh Multiselect - python-3.x

Question

My goal here was to create a Bokeh widgetbox which you could use to provide input to a form, however the only widgets that allow me to get my inputs back from Bokeh's javascript side into Python variables are RadioButtonGroups. Otherwise, Multiselect, AutocompleteInput, and others are ONLY able to return my input if it's in the form of an integer. This is being done in a Jupyter NB using Python and Bokeh 0.13.0, if you happen to have any questions or I've left anything out please don't hesitate to let me know.
Please see code below:
