_addFunctionCall method in Javascript
<p>Is there any method in JS named <code>_addFunctionCall</code> ? I came across following line in a legacy application.<br>
Method defination:  </p>

<pre><code>i2b2.ONT.ajax._addFunctionCall( "GetNameInfo",
                                "{{{URL}}}getNameInfo", 
                                i2b2.ONT.cfg.msgs.GetNameInfo,
                                null,
                                i2b2.ONT.cfg.parsers.ExtractConcepts);   
</code></pre>

<p>Method call:   </p>

<pre><code>var results = i2b2.ONT.ajax.GetNameInfo("ONT:FindBy", searchOptions);   
</code></pre>

<p>My another question is <code>GetNameInfo</code> method call contains only two parameters while it seems that method defination contains more than two parameters.So how things work here ?  </p>
