Get Selected Value from Drop-Down Inside sap.ui.table.Table - sapui5

Question

I have created a table with a drop-down control (sap.m.ComboBox). I am adding rows dynamically using JSONModel. Here is the logic to bind my table:
My Table bind logic.
Now, I am trying to get values from the table:
var oTable = this.getView().byId("mytable");
var data = oTable.getModel();
var len = oTable._iBindingLength; // Get total Line Items in table
for (var i = 0; i < len; i++) {
var _val1 = data.oData[i].item1;
var _val2 = data.oData[i].item2;
// my value logic here
}
But this is bringing all the values instead of just selected value from my drop-down control.

If you want to get selected key from the ComboBox (drop-down), bind the appropriate model data to its property selectedKey. Once the user selects something, the selected key will be stored in the model thanks to the two-way data binding.
<m:ComboBox width="100%"
selectedKey="{foo/selectedKey}"
items="{
path: 'foo/items',
templateShareable: false
}"
>
<core:Item key="{key}" text="{text}"/>
</m:ComboBox>
I've updated my example from your previous question: https://plnkr.co/edit/8YvXxk?p=preview
The model data is automatically updated when the user selects something from the drop-down:
