Solved: button click event inside iframe in html page

I have two html pages.

One page is called MainPage.html that contains an iframe.
The other page is called IframeContentPage.html which contains the content that is displayed in the iframe.

This is my code:

MainPage.html

When I run my page called MainPage.html it looks like this:

Inside the iframe I have a Bing button. If you press this button, it loads Bing into my iFrame.

Now if you notice, I have a button on this page MainPage.html called id="ButtonOutsideIframeBing" circled in blue in the picture above.
Is there a way to set the click event for this button so when I press it, it fires the click event of the Go To Bing button (circled in green in the pic above) inside the iFrame?
Either with JavaScripr or jQuery.

Anyone know the syntax to do that?
