Is there a better way to update my backing bean without submitting the form?

I have this p:inputTextarea:

<p:inputTextarea id="inputTextArea" value="#{myBean.data}" />

Since I moved the submitting form button elsewhere, myBean.data stays null when clicking on the button

So I did this:

<p:inputTextarea id="inputTextArea" value="#{myBean.data}}">
    <f:ajax event="blur" /> 
</p:inputTextarea>

which seems to work !

But I have a feeling that there is a more elegant way of doing this. I just need the value from the inputTextarea written to the bean, so that when I click a button in another form, the data will be available.

Any ideas ?

This is all kinda wrong. You have to understand the lifecycle of JSF. To make a short answer, on your button you should "process" "@this (the button itself) and inputTextArea". And then all will work alright. As a further performance improvement, you could use on the same button "partialSubmit= true" so that only the said fields (the input and the button) are submitted with the form. So you only need

<p:inputTextarea id="inputTextArea" value="#{myBean.data}" />

(no double brackets in the end) and then

<p:commandButton ..... process = "@this inputTextArea" .... partialSubmit = "true" />

But trust me, if you hit this (so simple) problem now ... you need to get a serious JSF book and start loving the Primefaces manual.
