Kendo Filter widget can support relative fields for filtering?

Question

I am trying to implement filter which can support relative fields i.e. the first field would be table names once user choose any table then second field gets populated with all columns available for selected table. Now users can choose operator and pass value for filtering the column value. So basically I want to filter on basis of column's value. As I dont want to put all columns for all tables in one field because that makes my drop down very long as I have huge columns in some table and also user wont be able to search specific column easily hence I want to introduce one more field which is table drop down. Once user select from table drop down then column dropdown will only have selected table column which reduce the columns number and user can choose easily. see the attached screenshot for same. So the expression preview should be something like . e.g. "table1.column5 is equal to myvalue". How we can achieve this ? I tried using editortemplate of field property of kendo Filter widget and added field 2 as shown in attached screen shot but after that not able to get field 2 value in expression. Can someone suggest what are the other ways we can achieve this ?
