调整按钮和input 的前后顺序

 <div class="input-group" component="$UI/system/components/bootstrap/inputGroup/inputGroup" xid="inputGroup1"> 
	<div class="input-group-btn" xid="div7"> 
		<a component="$UI/system/components/justep/button/button" class="btn btn-link" xid="button1" onClick="locationClick" icon="linear linear-book"> 
			<i xid="i15" class="linear linear-book"/>  
			<span xid="span20"></span>
		</a> 
	</div> 
	<input type="text" class="form-control" component="$UI/system/components/justep/input/input" xid="input4" bind-ref='$model.userData.ref("fAddress")'/>  
</div>
