Unable to search data from data grid

Hi, I am retrieving data from database. So whenever we retrieve a data from external database(here I am using mysql database)at that time the nanoflows for grid controls and data grid  are get created automatically in mendix. In that,their is inbuilt functionality of search & reset. My reset functinality is working but I am unable to search the record from various records. The nanoflow for searching records is as shown which is get created automatically when I am using a source of data grid as a microflow and this microflow contains execute query part which is used for retrieving the data.
