How to prevent screen to pull down on ios

Hello everyone, I spend last entire day researching for a solution for this problem that I’m not sure even if it’s possible to be solved!

While I was testing my grid, I was scrolling the data on the grid with the finger, and then I realize that some times when reach the end of the grid data, the screen starts “scrolling” too (vertically)!

So, my question is how to fix it ? How to Lock the screen to prevent this kind of issue ?

Note: You have a “gap” when you scroll up or down!

Didnt try it. So I don’t know if works.
Add it in config.xml

<preference name="DisallowOverscroll" value="true" />
<preference name="UIWebViewBounce" value="false" />

Thank you for the reply. But it does not work for me
