InputText isn't refreshed after valueChangeListener

I use the following valueChangeListener and submit on blur via javascript:

<h:inputText id="EAN" value="#

{LpChooseTypeForm.a_LpObject.a_niGloWa.a_EAN}

" valueChangeListener="#

{LpChooseTypeForm.a_LpObject.a_niGloWa.getSkuDetails}

"
onblur="this.form.submit();">

In the valueChangeListener I set some sku details and fill up new input fields:

<h:outputText id="SkuNr" value="#

{LpChooseTypeForm.a_LpObject.a_niGloWa.a_skuNo}

" />
<h:inputText id="SkuDescription" value="#

{LpChooseTypeForm.a_LpObject.a_niGloWa.a_skuDesc}

" />

but the "SkuDescription" inputText doesen't get updated. If I change "SkuDescription" to h:outputText it get's updated.
