Dynamic Loading Of <script>?

I have a code that adds dynamic text to a page:

Code:
document.getElementById("dynamic").innerHTML = text

However, sometimes the text contains actual javascript. It seems it won't run because the page already loaded.

add a child, etc. to get it running? The steps are: Display the part before the script. Run the script. Display the part after the script.

For example:

Code:
text = "display this text, run this code <script>alert('foobar')</script> and then display this text."
