ComboBox on change event in table

I have combo box bind to sapui5 table . Table has two columns and both are combo assume COLUMN1 and COLUMN2 . Based on the selection of COLUMN1 I want to change the list binding of COLUMN2 of respective row . Column 1 has type property bind to combo , based on type "edge" or "vertex" , it should filter the list of same type in COLUMN2  combo .  If edge type is selected in COLUMN1 , COLUMN2 combo should display list of edge type item , for that row only .
