In 8 entries, 2 entries text change event not triggered

In a Content View, we have 8 entries, which will change based on one picker. If pickers change the value all the 8 entries value would change, on first time we select the value from the picker all values set correctly, if the values selected previously now if we change the picker value the last two entries values are not changed but all other values are changed. All entries are setup same except the binding property and text change event but for last two text change event not triggered. On first time text change event trigger, we are not sure what causing this kind of issue can you please helps us with this.
