Event handler stuck after changing body.innerHTML

I would like to change some text in my body html with code below. Replacing works fine, but after that it seems to stuck, can't get out of function, so next parts of my script cannot be executed.

Nothing will happen after clicking .another-button. I think problem is with line that change body.innerHTML because when I delete this line everything works fine.

$(".do-replace-button").on("click", function () {
    //some different code
    document.body.innerHTML = document.body.innerHTML.replace(regExp, newWord);
}

$(".another-button").on("click", function (event) {
    //some code that won't execute
}
