#1033 Timebox doesn't update after clean the text

[Dennis Chen]

it is OK in 3.0.4 but fail in 3.0.5

step1. input a time and press tab, the label is changed
step2. clear the timebox and press tab, the label should update too.

<zk>
<label id="lab"/>
<separator/>
<timebox id="tb" onChange='lab.value="Time:"+tb.value'/>
</zk>
