I was able to come up with a solution by creating a parameter which the filter condition uses.
If the text field is updated on the form I
1, refresh my page adding that search param to the url.
2, before I init the viz, I check to see if that parameter exists.
3, if it exists I add it to the url that I use in my Viz creation call
4, create the Viz object which will initialize with the filtered text values displayed
