I have some problem in up and down key for the combo box
<combobox model="@load(user.practiceList)" id="cmbPractName"
cols="50" selectedItem="@bind(user.selectedPractice)"
onSelect="@command('onChange')" onChange="@command('onChange')"
disabled="@load(user.systemPractice)">
<template name="model" var="p">
<comboitem label="@bind(p.autoCompletionLabel)"
image="@load(p.isIS_ACTIVE() ? '../images/icon-enable.png' : '../images/icon-disable.png')"
value="@bind(p.PRACTICE_ID)" />
</template>
</combobox>
